1. What Internet Law Requires from Online Platforms and Where Section 230 Immunity Ends
Section 230 is the foundation of the modern internet. It is also the most commonly misunderstood legal protection in digital business.
Section 230(c)(1) provides that no provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider. This means a social media platform, a review website, a marketplace, or a forum is not liable for defamatory posts, fraudulent listings, or harmful content that third parties post on its service. Without Section 230, every platform that allows user-generated content would face unlimited liability for what its users say and do. Section 230 is what makes that business model legally sustainable.
Section 230 has statutory exceptions that courts have enforced strictly. Federal criminal law is not covered: a platform that knowingly facilitates sex trafficking violates FOSTA-SESTA, which created an explicit carve-out from the immunity. Intellectual property claims are also excluded, which is why copyright infringement claims against platforms are governed by the DMCA safe harbor rather than Section 230. The immunity does not protect a platform that creates or materially contributes to the allegedly illegal content, and courts have found that a platform crosses from protected passive hosting into unprotected content creation when it actively structures, shapes, or encourages harmful content in ways that go beyond neutral editing.
When Platforms Lose Section 230 Protection and What Conduct Triggers That Loss
The distinction between a protected interactive computer service and an unprotected content creator is the most litigated question in Section 230 jurisprudence, and the answer turns on how much the platform shaped the content at issue.
A platform that designs an algorithm to amplify certain types of harmful content, creates prompts or recommendation systems that generate third-party posts, or edits user content in ways that materially change its meaning may have crossed from hosting to creation. The Ninth Circuit's analysis in Roommates.com held that the platform lost Section 230 protection because it designed the questionnaire that produced discriminatory content, making the platform a co-creator rather than a passive host. Circuit courts have reached different conclusions in cases involving recommendation algorithms, finding that algorithm design does not automatically transform a platform into a content creator.
A platform that moderates content retains Section 230 immunity under § 230(c)(2) for good-faith moderation decisions, including removing content it considers objectionable. The immunity for moderation decisions is broad: a platform can remove content it finds harmful or against community standards without losing protection even if the removal decision was incorrect or inconsistent. This provision protects platforms from liability for over-moderation as well as for third-party content they did not create.
2. How DMCA Safe Harbor Protects Websites and What They Must Do to Keep It
The DMCA safe harbor is not automatic. It requires affirmative steps that many websites take incompletely or not at all.
To qualify for safe harbor protection under 17 U.S.C. § 512(c), an online service provider that hosts user-generated content must designate a copyright agent with the U.S. Copyright Office, publish that agent's contact information on its website, act expeditiously to remove or disable access to infringing content upon receiving a proper takedown notice, and not receive a financial benefit from infringing activity when the provider has the ability to control it. Each of these requirements is a condition, not a suggestion. A website that has not filed a DMCA agent designation with the Copyright Office, which costs $6 and requires renewal every three years, has no safe harbor protection regardless of how promptly it responds to takedown notices.
A valid DMCA takedown notice must identify the copyrighted work claimed to be infringed, identify the infringing material with enough specificity that the service provider can locate it, include the sender's contact information and a good faith belief statement, and include a statement under penalty of perjury that the information is accurate and that the sender is authorized to act for the copyright owner. A website that receives a valid takedown notice and removes the content has acted within the safe harbor. A website that receives a valid notice and ignores it has stepped outside the safe harbor for that content. Keeping the agent registration current, processing takedown notices promptly, and evaluating counter-notices from users who dispute the removal are the three operational tasks that DMCA compliance requires on an ongoing basis once a site begins hosting user-uploaded content.
Online Defamation and How Internet Law Handles Harmful Content about Real People
Online defamation claims are among the most frequently pursued internet law claims, and they collide directly with Section 230's platform immunity in ways that produce inconsistent results depending on who the plaintiff is suing.
A defamation claim against the person who posted the harmful content is not affected by Section 230, which protects platforms, not the individual posters themselves. A claim against the platform that hosted the content is almost always defeated by Section 230 unless the platform created or materially contributed to the defamatory content. This structure means that defamation plaintiffs must identify and sue the actual poster, which in anonymous online environments requires a court order compelling the platform to disclose the poster's identity.
Subpoenas to identify anonymous online posters require the plaintiff to file a John Doe lawsuit, obtain a subpoena directed to the platform, and in many jurisdictions satisfy a standard that balances the plaintiff's right to seek redress against the poster's First Amendment right to speak anonymously. Courts in different jurisdictions apply different standards for these subpoenas, ranging from a good faith basis test to a higher prima facie showing of defamation. Internet defamation and online defamation claims require navigating both the substantive defamation analysis and the procedural challenge of identifying who actually made the statement.
| Internet Law Issue | Primary Legal Framework | Platform Vs. User Liability | Key Compliance Requirement |
|---|---|---|---|
| Third-party harmful content | Section 230, 47 U.S.C. § 230 | Platform protected; poster directly liable | Do not create or materially contribute to content |
| Copyright infringement by users | DMCA § 512, 17 U.S.C. § 512 | Platform protected if safe harbor maintained | DMCA agent registration; prompt takedown response |
| Children's data collection | COPPA, 15 U.S.C. § 6501 | Operator directly liable | Verifiable parental consent before collecting data |
| Website accessibility | ADA Title III | Website operator directly liable | WCAG 2.1 AA compliance; accessible design |
Domain name disputes under the Anti-Cybersquatting Consumer Protection Act at 15 U.S.C. § 1125(d) allow trademark owners to sue parties who register domain names that are identical or confusingly similar to their marks with a bad faith intent to profit. ACPA provides statutory damages of $1,000 to $100,000 per domain name, in rem proceedings against the domain name itself when the registrant cannot be found, and transfer of the domain to the trademark owner as a remedy. The UDRP administered by ICANN provides a faster administrative alternative: a UDRP proceeding typically resolves in 60 days, costs significantly less than federal litigation, and produces a transfer order if the complainant establishes that the domain is confusingly similar to its mark, the registrant has no legitimate interest in the domain, and the domain was registered and used in bad faith.
3. Direct Liability in Internet Law for Data Collection, Accessibility, and Privacy Obligations
Platform immunity is only one layer of internet law. Websites also face direct liability for how they collect data, design access, and use domain names, and these obligations apply regardless of whether the site hosts any user-generated content at all.
For many commercial websites, a privacy policy is required by state privacy statutes or becomes legally necessary because the site's actual data practices must match what it tells users. The California Consumer Privacy Act and the growing number of state privacy laws modeled on it require businesses meeting specific size thresholds to disclose the categories of personal information collected, the purposes for which it is used, the categories of third parties with whom it is shared, and the consumer's rights to access, delete, and opt out of the sale of their personal information. A website that collects email addresses, browsing data, or purchase history from California residents and does not maintain a compliant privacy policy is in violation regardless of where the website is based. Virginia, Colorado, Connecticut, and Texas have each added their own requirements, creating compliance obligations that apply to any website serving users nationally.
COPPA at 15 U.S.C. § 6501 et seq. .mposes strict requirements on websites directed to children under 13 or that knowingly collect personal information from children under 13. COPPA requires verifiable parental consent before collecting any personal information from a child, a clear and comprehensive privacy policy, the right of parents to review and delete information collected about their children, and prohibition on conditioning a child's participation on providing more information than reasonably necessary. The FTC has assessed civil penalties up to $50,120 per COPPA violation and has brought enforcement actions against major platforms that failed to treat users as children when the platform knew or should have known children were using it. Data privacy compliance programs for websites with any exposure to younger users require a specific COPPA analysis separate from the general state privacy law framework.
Ada Website Accessibility and Why Web Accessibility Lawsuits Have Increased Sharply
Title III of the Americans with Disabilities Act requires places of public accommodation to be accessible to individuals with disabilities. Courts have increasingly applied this requirement to commercial websites, and web accessibility lawsuits have grown significantly as plaintiffs' firms have developed efficient litigation programs targeting non-compliant sites.
A website that is inaccessible to individuals who use screen readers, keyboard-only navigation, or other assistive technologies may violate the ADA if the site qualifies as a place of public accommodation. Federal circuit courts have split on whether a website must have a nexus to a physical place of business to qualify under Title III, but in circuits that apply the nexus requirement, e-commerce sites with physical stores, restaurants with online ordering, and similar businesses have consistently been found covered.
The Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA compliance is the standard most commonly used to evaluate ADA accessibility. A website that cannot be navigated using a keyboard alone, that has images without alternative text, videos without captions, or forms with inaccessible labels has likely failed WCAG 2.1 AA standards and is vulnerable to an accessibility demand or lawsuit. Most web accessibility cases settle before trial, but defense costs and plaintiff's attorney fee exposure make them commercially significant even when the underlying issue can be remediated quickly. Cybersecurity and data privacy and website compliance audits increasingly include accessibility review alongside data privacy review, because both create direct operator liability independent of any platform immunity analysis.
4. Frequently Asked Questions about Internet Law
Internet law questions arrive from website owners who received a DMCA takedown notice and do not know whether to comply or dispute it, from platform operators named in a lawsuit for content a user posted, from e-commerce businesses that discovered their privacy policy does not cover the state laws that now apply to their customer base, and from business owners whose competitor registered a domain name confusingly similar to their trademark. Those situations generate the following questions.
What Is Section 230 and Does It Protect My Website from Lawsuits over User Content?
Section 230 of the Communications Decency Act provides that online platforms are not treated as the publisher or speaker of third-party content users post on their services. This means your platform is generally not liable for defamatory, harmful, or offensive content users post, as long as your platform did not create or materially contribute to that content. Section 230 does not cover federal criminal law violations, intellectual property claims, or conduct that transforms your platform from a passive host into a content creator. Platforms that actively shape, promote, or algorithmically amplify harmful content face closer scrutiny on whether they remain within the immunity.
What Must I Do to Maintain DMCA Safe Harbor Protection for My Website?
To maintain DMCA safe harbor protection under 17 U.S.C. § 512, you must register a designated copyright agent with the U.S. Copyright Office and renew the registration every three years, publish the agent's contact information on your website, act expeditiously to remove infringing content when you receive a valid takedown notice, and avoid directly profiting from infringing activity you have the ability to control. A website that has not registered its DMCA agent has no safe harbor protection. When you receive a valid DMCA notice, you must act promptly; ignoring it removes the safe harbor for that specific content.
Does My Website Need a Privacy Policy and What Must It Contain?
For many commercial websites, a privacy policy is legally required or becomes necessary because data collection practices must match what the site tells users. California's CCPA requires businesses meeting specific thresholds to maintain a compliant privacy policy disclosing data collection categories, purposes, third-party sharing, and consumer rights, regardless of where the business is based. Multiple other states have enacted similar laws. COPPA separately requires a specific privacy policy for websites directed to children or that knowingly collect information from users under 13, with additional parental consent obligations that go beyond a general privacy policy.
Can I Be Sued If My Website Is Not Accessible to People with Disabilities
Yes. Courts have increasingly applied the ADA Title III public accommodation requirement to commercial websites, particularly those with a nexus to a physical business location. Web accessibility lawsuits have increased significantly. WCAG 2.1 Level AA compliance is the generally accepted accessibility standard. A website that fails basic accessibility tests, such as missing image alt text, videos without captions, or unlabeled form fields, is vulnerable to a demand letter or lawsuit regardless of whether the website owner was aware of the requirements.
What Can I Do If Someone Registered a Domain Name Similar to My Trademark?
Two main options exist. You can file a complaint under the Uniform Domain-Name Dispute-Resolution Policy administered by ICANN, which provides an expedited proceeding typically resolving within 60 days. To prevail, you must show the domain is confusingly similar to your mark, the registrant has no legitimate interest in the domain, and the domain was registered and used in bad faith. Alternatively, you can sue under the Anti-Cybersquatting Consumer Protection Act at 15 U.S.C. § 1125(d) in federal court, which provides statutory damages of $1,000 to $100,000 per domain and allows in rem proceedings against the domain itself when the registrant cannot be located. UDRP is faster and cheaper; ACPA litigation provides damages and a stronger evidentiary record.
