Freedom of speech does apply to social media, but probably not the way you think: the First Amendment restrains the government, not the private companies that run these platforms. So when Facebook, X, YouTube, TikTok, or Instagram removes your post, hides a reply, or suspends your account, no constitutional right has been violated. The platform is enforcing its own rules on its own service. The Constitution steps in only when a government actor is doing the restricting.
Why the First Amendment Doesn’t Bind Platforms
The First Amendment says “Congress shall make no law … abridging the freedom of speech.”1Cornell Law School / Legal Information Institute. First Amendment Through the Fourteenth Amendment, that limit reaches every level of government: federal, state, and local. It does not reach private individuals, private businesses, or private organizations.
Courts call this the state action doctrine. Constitutional free speech protections kick in only when the government is the party doing the restricting. A city council that deletes critical comments from its official page raises a First Amendment problem. A social media company that removes the same comment under its harassment policy does not. The company is making a private editorial decision, and the Constitution is silent on it.
The “Modern Public Square” Line Is Widely Misread
You have probably heard social media called “the modern public square.” That phrase comes from the Supreme Court’s 2017 decision in Packingham v. North Carolina, where Justice Kennedy described social media platforms as among “the principal sources for knowing current events, checking ads for employment, speaking and listening in the modern public square.”2Justia Law. Packingham v. North Carolina, 582 US (2017)
The case was about a state law that blocked certain people from accessing social media at all. The Court held that the government cannot cut people off from these channels. It said nothing about what private platforms must allow. Packingham limits the government; it does not force Facebook to host your post.
Platforms Have Their Own Free Speech Rights
Here is the part that surprises people: social media companies do not just lack First Amendment duties to their users, they have First Amendment rights of their own. A platform’s choices about what content to carry, remove, promote, or bury are treated as protected editorial judgment, similar to a newspaper deciding which letters to print or a bookstore choosing which books to stock.
The Supreme Court made this explicit in Moody v. NetChoice, decided in July 2024. Writing for the Court, Justice Kagan held that “the government may not, in supposed pursuit of better expressive balance, alter a private speaker’s own editorial choices about the mix of speech it wants to convey.”3Supreme Court of the United States. Moody v. NetChoice LLC, No. 22-277
The case involved laws from Florida and Texas that tried to stop large platforms from removing content based on a user’s political viewpoint. Both states argued the biggest platforms had grown so dominant they should be regulated like utilities. The Court rejected that framing. Editorial freedom, the Court explained, “does not change because the curated compilation has gone from the physical to the virtual world.”3Supreme Court of the United States. Moody v. NetChoice LLC, No. 22-277 States cannot override how a platform curates its main feeds.
The Real Rulebook: Terms of Service
The mechanism platforms actually use to police content is the contract you agreed to when you signed up. Terms of Service, sometimes labeled community standards or community guidelines, spell out what the platform allows and what it will remove, covering harassment, threats, graphic content, misinformation, spam, and more.
When a post is removed or an account is suspended, the platform is enforcing that contract. This is ordinary contract law, not a constitutional dispute, and courts treat it that way. Most Terms of Service give the company broad, near-total discretion to remove content or terminate accounts for almost any reason. Users who sue for breach of contract after a suspension typically discover that the terms they clicked through gave the platform exactly the authority it used.
Section 230 Adds Another Layer of Protection
Beyond the First Amendment, a federal statute reinforces platforms’ ability to moderate. Section 230 of the Communications Decency Act, passed in 1996, does two things. It says “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,” which shields platforms from being sued over what users post. It also protects platforms that in good faith take down content they consider objectionable, insulating those moderation decisions from liability.4Office of the Law Revision Counsel. 47 USC 230 – Protection for Private Blocking and Screening of Offensive Material
Section 230 is broad but not unlimited. It does not block federal criminal prosecution, so a platform that knowingly facilitates crimes like child exploitation or obscenity can still be charged. It does not affect intellectual property law, so copyright and trademark claims proceed under their own rules. A 2018 statute known as FOSTA-SESTA carved out sex trafficking, allowing federal and state criminal cases and civil suits over trafficking conducted through platforms. And Section 230 does not override federal or state wiretapping and electronic surveillance laws.4Office of the Law Revision Counsel. 47 USC 230 – Protection for Private Blocking and Screening of Offensive Material
For the everyday content moderation disputes most users care about, a deleted post or a suspended account, Section 230 gives the platform wide latitude on top of its constitutional protection.
Where the First Amendment Does Reach Social Media
There is one important corner of social media where the First Amendment does apply: when a government official uses an account for official business. If a mayor, police chief, or city manager runs a page that announces policy, shares agendas, and responds to residents in an official capacity, blocking a critic or deleting a dissenting comment can be unconstitutional viewpoint discrimination.
The Supreme Court set the current test in Lindke v. Freed, decided in March 2024. A public official’s social media activity counts as government action only if the official (1) had actual authority to speak on the government’s behalf about the subject of the post, and (2) purported to exercise that authority in the post itself.5Supreme Court of the United States. Lindke v. Freed, No. 22-611 Both prongs must be met.
An off-duty officer posting personal restaurant reviews is not engaged in state action. A police chief using an account to issue department updates, respond to public safety questions, and share official press releases likely is. On that kind of account, the official cannot block residents for critical comments or delete replies just because they express disagreement. Content-neutral moderation, such as removing spam or threats, is still allowed; viewpoint-based moderation is not. The analysis is fact-specific, and a mixed account can be evaluated post by post rather than as a whole.
What You Can Do If Your Content Is Removed
Understanding the law does not make it less frustrating when a post disappears, but it does shape what actually works.
Start with the platform’s own appeals process. Every major service has one, and appeals succeed more often than people expect, especially when the initial removal came from an automated system. A human review can reverse a bad call.
For Meta’s platforms, including Facebook, Instagram, and Threads, there is a second layer. After you exhaust Meta’s internal appeals, you can submit your case to the independent Oversight Board, which reviews whether Meta’s decision matched its own policies and human rights commitments. The Board’s rulings are binding on Meta for that specific case, though its broader policy recommendations are not.
Suing a platform over a content removal is generally not a realistic path. Courts have consistently upheld platforms’ First Amendment rights and Section 230 protections around moderation. A breach-of-contract claim is theoretically available if a platform clearly violated its own Terms of Service, but those terms are drafted to give the company nearly unlimited discretion, and such claims rarely succeed.
The picture changes if the account that blocked you or deleted your comments belongs to a government official acting in an official capacity. That is where the Lindke framework applies, and viewpoint-based blocking by public officials has been successfully challenged in court.5Supreme Court of the United States. Lindke v. Freed, No. 22-611 That is a First Amendment case. A fight with a private platform is not.
