Section 230 for forum owners: what it protects and what it doesn't

If you run a forum, your members write most of what's on it. Section 230 of the Communications Act is the U.S. law that decides, in most cases, who is legally responsible for those posts. Knowing what it covers (and what it doesn't) helps you moderate with confidence.

Key takeaways

Section 230(c)(1): you generally aren't treated as the publisher or speaker of what your members post.
Section 230(c)(2): good-faith moderation of objectionable content doesn't create liability on its own.
It does not cover federal criminal law, intellectual property (copyright), communications privacy law, or certain sex-trafficking claims.

The two key sentences

The statute, 47 U.S.C. 230 (Cornell LII), says in subsection (c)(1): "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." For a forum, that means a defamatory post written by a member is generally the member's legal problem, not the forum owner's.

Subsection (c)(2) protects moderation. A provider or user can't be held liable on account of "any action voluntarily taken in good faith to restrict access to or availability of material" it considers obscene, harassing, excessively violent or "otherwise objectionable," whether or not that material is constitutionally protected. In other words, deleting spam or removing a nasty thread doesn't turn you into the publisher of everything you didn't delete.

The Electronic Frontier Foundation's overview, EFF: Section 230, explains why this matters for small sites in particular: without it, every forum, comment section and review site would face legal risk for each post a visitor writes.

What Section 230 does not cover

Subsection (e) lists exceptions. Section 230 does not:

Impair federal criminal law, including laws on obscenity and the sexual exploitation of children.
Limit or expand intellectual property law. Copyright complaints are handled under a different law, the DMCA; see our guide to registering a DMCA designated agent.
Limit communications privacy law, including the Electronic Communications Privacy Act.
Limit certain sex-trafficking claims under federal law and consistent state law.

It also doesn't protect content you write. If you, an admin, or a staff account posts something, you are the "information content provider" for that post.

Practical steps for forum owners

Publish clear rules and enforce them consistently (start from our forum rules template).
Moderate in good faith. Remove spam, harassment and illegal content promptly (see the moderation guide).
Set up a DMCA process for copyright complaints, because Section 230 doesn't cover them.
Label staff accounts clearly, so it's obvious which posts come from the site itself.
Keep records of reports and actions taken.
Handle privacy obligations separately (see GDPR and COPPA for forums).

Section 230 is U.S. law and is often the subject of court cases and proposed changes in Congress. Other countries have different rules, so if many of your members are abroad, check those too.
