The Two Key Clauses of Section 230: Why Platforms Are Not Liable for User Content or Good-Faith Moderation

On May 24, 1995, a New York Supreme Court judge issued a ruling that threatened to make the nascent internet legally impossible to operate. The investment firm Stratton Oakmont—later made famous in the film The Wolf of Wall Street—had sued the online service provider Prodigy over an anonymous message board post claiming the firm was committing criminal fraud. The judge ruled that because Prodigy actively used "Board Leaders" and screening software to delete offensive notes, it exercised editorial control. By trying to clean up its platform, Prodigy had legally become a publisher, making it liable for every defamatory statement its users posted.[4]

That ruling created a perverse incentive for the technology industry. If a platform attempted to moderate its community, it assumed total legal liability for millions of user-generated messages. If it buried its head in the sand and did nothing, it remained a mere distributor—like a newsstand—and escaped liability entirely.[4]

To fix this, the United States Congress passed the Communications Decency Act in 1996. While the Supreme Court struck down the act's anti-obscenity provisions a year later on First Amendment grounds, one specific piece of the legislation survived: 47 U.S.C. § 230.[1]

Today, Section 230 is frequently debated by politicians as a monolithic shield that grants technology companies unchecked power. In reality, the statute operates through two distinct, highly specific clauses that perform entirely different legal functions. The first protects what platforms leave up; the second protects what they take down.[1][6]

The first clause is Section 230(c)(1), the liability shield. The text states 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."[1][2]

In practice, this means that if a user posts a defamatory review on Yelp, uploads a harassing video to YouTube, or writes a libelous post on X, the platform cannot be sued for the content. The legal responsibility rests entirely with the person who created the speech. This clause allows platforms to host massive volumes of user-generated content without needing to pre-screen every submission to avoid bankruptcy.[2][5]

The second clause is Section 230(c)(2), often called the Good Samaritan provision. It states that platforms cannot be held liable for "any action voluntarily taken in good faith to restrict access to or availability of material" that the provider considers "obscene, lewd, lascivious, filthy, excessively violent, harassing, or otherwise objectionable."[1][3]

This is the moderation shield. It directly overrules the Stratton Oakmont decision by ensuring that a platform does not become a publisher simply because it enforces community guidelines. If a social media network deletes a violent video or bans a user for harassment, the user cannot successfully sue the platform for restricting their speech.[3][4]

The distinction between the two clauses is frequently lost in public discourse. When lawmakers argue that platforms should lose their Section 230 protections for censoring political speech, they are targeting the moderation protections of the second clause. When critics argue that platforms should be sued for allowing harmful algorithms or dangerous challenges to proliferate, they are challenging the liability shield of the first clause.[3][5]

The statute is not absolute. Section 230 explicitly excludes federal criminal law, meaning platforms can be prosecuted by the Department of Justice for knowingly hosting illegal material. It also excludes intellectual property claims, which are governed separately by the Digital Millennium Copyright Act.[2][6]

Furthermore, in 2018, Congress passed the FOSTA-SESTA package, which carved out an exception to Section 230 for platforms that knowingly facilitate sex trafficking. This marked the first time the 1996 liability shield was legislatively narrowed.[6][7]

Despite ongoing calls for reform, the core architecture of the internet remains dependent on these two clauses. The 26 words of the liability shield allow platforms to exist, while the Good Samaritan protections allow them to curate their spaces. Any alteration to either clause would fundamentally change how digital communities operate.[2][6]
