Zeran v. America Online was the first federal appeals court decision to interpret Section 230, the 1996 law that protects online services from lawsuits over what their users post. The court read that protection broadly, and its 1997 ruling became the foundation for nearly three decades of decisions shielding internet companies. It is also the starting point for understanding the defense social media companies raise against families today.

What Happened
In April 1995, days after the Oklahoma City bombing, an anonymous user posted a message on an America Online bulletin board advertising T-shirts with offensive slogans about the bombing. The post told readers to call “Ken” and listed the home phone number of Kenneth Zeran, a Seattle man who had nothing to do with it.
Zeran was flooded with angry calls and death threats. He called AOL, which said it would remove the post but refused to post a retraction. New posts appeared the next day and kept coming for days. In early May, an Oklahoma City radio host read the first message on the air and urged listeners to call, and the threats grew worse.
The Lawsuit and Section 230
Zeran sued AOL, arguing that once he told the company about the posts, it was responsible for acting quickly to remove them, posting a correction and screening for more. AOL responded that Section 230 barred the lawsuit.
Section 230 was a brand new law, passed in early 1996. Congress wrote it partly in response to a New York court decision that held an online service responsible for a user’s post because the service moderated its message boards. Lawmakers worried that ruling would discourage online services from removing offensive material. Section 230 says an online service should not be treated as the publisher of information provided by someone else.
What the Court Decided
A federal court in Virginia dismissed Zeran’s case, and in November 1997, the federal appeals court for the Fourth Circuit agreed. The court held that Section 230 bars any claim that would treat an online service as the publisher of a user’s content, including decisions about whether to post, remove or edit it.
Zeran argued that AOL should at least be responsible once it had been told about the posts, the way a bookstore can be responsible for selling a book it knows is defamatory. The court rejected that argument too. It reasoned that holding services responsible after notice would push them to remove anything anyone complained about, and that Congress meant to protect them from that pressure. The Supreme Court declined to hear the case.
Why It Mattered
Courts across the country followed Zeran, and Section 230 became one of the most powerful protections in American law. It allowed message boards, review sites, video platforms and social networks to grow without being sued over every post, and it is often credited with making the modern internet possible. Critics argue the courts read the law far more broadly than Congress intended, leaving people harmed online with no one to hold responsible. The Supreme Court had a chance to narrow Section 230 in 2023 but declined to decide the question.
Section 230 and the Social Media Addiction Lawsuits
Meta, TikTok, Snap and Google have relied on Section 230 in the lawsuits brought by families who say social media harmed their children. The companies argue that the claims are really about the content children saw, which other users posted.
The families’ claims focus on something different: the companies’ own conduct in designing their apps and in failing to warn parents about the risks. Courts have drawn lines. The federal judge overseeing the nationwide cases ruled in 2023 that Section 230 bars some claims, such as those about endless feeds, but not others, including claims about weak age checks, inadequate parental controls and failure to warn. Those claims have moved forward, and juries have begun hearing similar claims, starting with a 2026 trial in California state court.

Common Questions
What is Section 230?
A 1996 federal law that says an online service should not be treated as the publisher of information provided by its users. It protects websites and apps from many lawsuits over what users post.
What did Zeran v. America Online decide?
In 1997, the Fourth Circuit held that Section 230 barred Kenneth Zeran’s lawsuit against AOL over anonymous posts that listed his phone number, even though he had told AOL about them.
Why wasn’t AOL responsible after it was told about the posts?
The court reasoned that making services responsible once they receive a complaint would push them to remove anything anyone objected to, and that Section 230 was meant to prevent that.
Does Section 230 block the social media addiction lawsuits?
Not entirely. Courts have ruled that it bars some claims tied to content other users posted, but claims about the companies’ own design choices, such as weak age checks and inadequate parental controls, and their failure to warn families have been allowed to go forward.
Has the Supreme Court ruled on Section 230?
Not directly. In 2023, it took up a case about whether Section 230 protects YouTube’s recommendations but decided it without answering that question.
