This is Class 4.2 of roughly 30 in Nita Farahany's Advanced Topics in AI Law and Policy course, published February 11, 2026. It is the course's Section 230 doctrine class, walking through the structure of 47 U.S.C. § 230, its origin in the Stratton Oakmont problem, the Zeran baseline, the erosion of the platform/publisher distinction, and the Lemmon v. Snap product-design carve-out that the class describes as the foundation of every successful platform-liability case in MDL 3047 and the LA bellwether trial.
Statutory structure
The class identifies two operative provisions of § 230. Section 230(c)(1) supplies the immunity: "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." Section 230(c)(2) is the "Good Samaritan" provision, which protects platforms from liability for removing objectionable content in good faith.
Origin: the Stratton Oakmont problem
According to the class, § 230 (enacted 1996) was a response to the trap created by Stratton Oakmont v. Prodigy Services (N.Y. 1995). That decision held that a platform that moderated content was a "publisher" liable for what it failed to remove, while a platform that didn't moderate was a mere "distributor" with no liability. The result was an incentive to do nothing, which § 230 was enacted to break.
The Zeran baseline
Zeran v. AOL (4th Cir. 1997) established the baseline the class works from: § 230 is "broad immunity" extending beyond defamation to any cause of action that treats the platform as the publisher of third-party content.
Erosion of the platform/publisher distinction
The class argues that in 1996 "publisher" had a relatively clear meaning, but that by 2026 the central unresolved doctrinal question is whether algorithmic ranking, recommendation, and amplification turn the platform into a "co-creator" of the speech.
The Lemmon v. Snap carve-out
Lemmon v. Snap (9th Cir. 2021) is presented as the doctrinal turning point. The plaintiff's son died in a 113 mph car crash while using Snapchat's "Speed Filter," which gamified high-speed driving. Snap invoked § 230. The Ninth Circuit held that a product-design claim — that the Speed Filter incentivizes dangerous behavior — is not a publisher-liability claim about content, and that § 230 does not bar it. The class describes this carve-out as the foundation of MDL 3047 and of every social-media product-design suit.
What survives and what § 230 still bars
The class catalogs the claims that survive § 230: product-design claims that do not depend on third-party content (per Lemmon); failure-to-warn claims, which some courts have allowed; and claims based on promises made by the platform itself, such as misleading community-standards representations (the FTC fraud theory). It contrasts these with claims § 230 still bars: defamation, intentional infliction, and similar torts where the harm is the content itself, and most claims that a platform "should have removed X."
