Section 230 and Content Moderation: What Protects Your Platform When Users Post and When Protection Ends

By Hank FasthoffJuly 6, 2026

If your online business allows users to post content, whether that's product reviews, comments, forum discussions, marketplace listings, or social media posts, Section 230 of the Communications Decency Act (47 U.S.C. § 230) is the statute that determines whether you're liable for what they say. Without Section 230, every website that hosts user-generated content could be treated as the publisher of that content and held responsible for defamation, fraud, harassment, or any other claim arising from something a user posted. With Section 230, the platform generally isn't liable for third-party content, and it can moderate that content without losing its protection.

Section 230 is the legal infrastructure that allows comment sections to exist, lets review sites host negative reviews without being sued for defamation, and lets marketplaces list third-party products without becoming liable for every seller's representations. Any business that hosts user-generated content relies on Section 230, whether it knows it or not.

The Two Protections

Section 230 contains two operative provisions that work together. One protects hosting. The other protects moderating.

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." In practice, this means that if a user posts a defamatory review on your marketplace, a fraudulent listing on your platform, or harassing content in your forum, you aren't treated as the publisher of that content. You're protected from civil liability for the user's speech because you didn't create it.

An "interactive computer service" is defined broadly as "any information service, system, or access software provider that provides or enables computer access by multiple users to a computer server." This covers social media platforms, marketplace websites, review sites, blog comment sections, email providers, cloud storage services, and essentially any online service that allows users to post or transmit content.

Section 230(c)(2) provides the "Good Samaritan" protection. It immunizes providers from liability for "any action voluntarily taken in good faith to restrict access to or availability of material that the provider considers to be obscene, lewd, lascivious, filthy, excessively violent, harassing, or otherwise objectionable, whether or not such material is constitutionally protected." In practice, this means you can moderate content (remove posts, suspend accounts, filter objectionable material) without losing your (c)(1) immunity. Before Section 230, a platform that moderated content could be treated as an editor (and therefore liable for everything it chose not to remove). Section 230(c)(2) eliminated that dilemma by protecting moderation decisions made in good faith.

What Section 230 Protects

Section 230 immunity applies to any claim that would treat the platform as the publisher or speaker of third-party content. Courts have applied it to defamation claims (a user posts a false and damaging statement about another person or business), fraud claims (a user posts a misleading product listing or deceptive advertisement), negligence claims (a plaintiff argues the platform should have removed harmful content), breach of contract claims based on content moderation decisions (a user argues the platform wrongly removed their post or suspended their account), and product liability claims premised on the platform's role in listing or displaying third-party products.

In Force v. Facebook, Inc., 934 F.3d 53 (2d Cir. 2019), the Second Circuit held that Facebook's use of algorithms to organize and recommend user-generated content didn't forfeit Section 230 immunity. Algorithmic amplification of third-party content is still "publishing" under the statute, and a platform that recommends user content through an algorithm isn't treated as the creator of that content. In Gonzalez v. Google LLC, 598 U.S. 617 (2023), the Supreme Court vacated the lower court's ruling and remanded without reaching the algorithmic recommendation question, effectively leaving the Force framework in place.

What Section 230 Doesn't Protect

Section 230 has five categories of exceptions where the immunity doesn't apply.

Content the platform creates or materially contributes to developing. Section 230 protects platforms from liability for third-party content only. If the platform creates the content itself, writes the product description, edits a user's post in a way that adds new defamatory meaning, or provides the tools and structure that materially contribute to the illegality of the content, the platform becomes an "information content provider" and loses immunity for that specific content. Hosting and organizing third-party content isn't material contribution. Designing features that require users to provide information in a way that makes the resulting content illegal (as in Fair Housing Council of San Fernando Valley v. Roommates.com, 521 F.3d 1157 (9th Cir. 2008), where the site required users to answer questions that violated fair housing laws) crosses the line.

Federal criminal law. Section 230(e)(1) preserves all federal criminal law. If user-generated content on your platform violates a federal criminal statute, Section 230 doesn't prevent federal prosecution of the platform.

Intellectual property claims. Section 230(e)(2) preserves intellectual property law. Copyright infringement claims, trademark infringement claims, and other IP claims proceed without Section 230 immunity. (For copyright specifically, the DMCA's separate safe harbor under 17 U.S.C. § 512 provides its own immunity framework for platforms that comply with notice-and-takedown requirements.)

Sex trafficking (FOSTA-SESTA). In 2018, Congress amended Section 230 through the Allow States and Victims to Fight Online Sex Trafficking Act (FOSTA-SESTA) to remove immunity for platforms that knowingly facilitate sex trafficking. Section 230(e)(5) allows civil claims under 18 U.S.C. § 1595 (the federal trafficking victim statute) and state criminal prosecutions for conduct that violates federal anti-trafficking laws.

Electronic Communications Privacy Act. Section 230(e)(4) preserves claims under ECPA (18 U.S.C. §§ 2510-2522) and similar state wiretapping and electronic surveillance laws.

Product Design Versus Publishing

Plaintiffs have increasingly attempted to reframe publishing-based claims as "product design" or "failure to warn" claims to avoid Section 230. Courts have responded with a functional analysis: if the claim, regardless of how it's labeled, would require the platform to monitor, moderate, or restrict user-generated content, it's a publishing claim and Section 230 applies.

In Doe v. Grindr (9th Cir. 2025), the plaintiff alleged negligent design of the dating app's matching and messaging features. The Ninth Circuit held that the matching and messaging features were "neutral" communication tools, and claims requiring the platform to suppress communications between users or warn of misuse were inherently tied to the platform's publishing function.

In Lemmon v. Snap, Inc. (9th Cir. 2021), by contrast, the court allowed a negligence claim to proceed against Snapchat based on its Speed Filter feature (which displayed how fast the user was traveling and allegedly incentivized dangerous driving). The court distinguished the Speed Filter from content moderation because the Speed Filter was a standalone product feature unrelated to publishing third-party speech.

For platform operators, the practical takeaway is that features enabling user communication are protected under Section 230, while standalone product features that create independent risks may not be.

Content Moderation in Practice

Section 230(c)(2) provides platforms wide latitude to moderate, but moderation policies should be documented, consistently applied, and designed to demonstrate good faith.

Publish and enforce community guidelines. Written guidelines that define prohibited content (spam, harassment, illegal activity, fraud, IP infringement) and describe the consequences of violation (content removal, account suspension, permanent ban) provide the framework for consistent moderation. Undocumented, ad hoc moderation decisions are harder to defend if challenged.

Don't promise more than you can deliver. Vague assurances of a "safe environment" or guarantees of "trusted content" in your terms of service can create expectations that exceed what your moderation team can enforce. In Doe v. Grindr, the Ninth Circuit noted that vague safety assurances were "too general to be enforceable" as promises. Keep your terms of service accurate about what moderation you provide without implying that you guarantee the safety or accuracy of user-generated content.

Respond to reports and complaints. A platform that ignores user reports of illegal content or harmful activity doesn't lose Section 230 immunity automatically (because immunity doesn't depend on content moderation performance), but failing to act on credible reports of criminal activity can create exposure under theories that Section 230 doesn't cover, such as FOSTA-SESTA for sex trafficking or failure-to-warn claims based on knowledge of specific, identifiable threats.

Practical Recommendations

Draft your terms of service and community guidelines with Section 230 in mind. Reserve broad discretion to remove content and suspend accounts, disclaim any obligation to monitor user content, and avoid language that guarantees the accuracy, safety, or legality of third-party content.

Don't edit user content in ways that add new meaning. Reorganizing, reformatting, and displaying user content is protected publishing activity. Rewriting a user's review, adding text to a user's listing, or modifying user content in a way that creates new defamatory or misleading statements can make the platform a co-creator of the content and forfeit immunity.

Maintain a DMCA-compliant takedown process. Section 230 doesn't protect against intellectual property claims, and the DMCA's § 512 safe harbor requires registering a designated agent, publishing a policy for terminating repeat infringers, and expeditiously removing infringing material upon receipt of a compliant notice.

Monitor legislative developments. Congress has not passed major Section 230 reform since FOSTA-SESTA in 2018, but a bipartisan group of ten senators introduced the Sunset Section 230 Act in December 2025, which would repeal Section 230 entirely with a two-year effective date (targeting January 1, 2028). Whether that bill or an alternative passes is uncertain, but the political pressure on Section 230 is the most intense it's been since the statute was enacted. Platform operators should plan for a future in which the current scope of immunity may be narrower than it is today.
