Does posting a “legal notice” stop Meta from using your photos and posts?

The claim: A long text, often starting with "Goodbye Meta AI" or "I do not give Facebook or any entities associated with Facebook permission to use my pictures...", says that copying it onto your profile legally prevents Meta from using your photos and posts.

I counted it on five of my friends' stories in a single evening.

What we found

• Versions of this post have circulated since 2012, and fact-checkers have repeatedly rated them false.
• Posting a statement on your own profile doesn't change the terms you accepted when you created your account.
• Under Facebook's terms, you already own the content you post. What Meta can do with it depends on those terms and on your settings, not on a post.

Verdict

False. Copying the notice has no legal effect.

What actually helps

• Review your privacy settings and who can see your posts.
• Look for the official settings and forms Meta provides about how your information is used, where they're available in your country.
• Think before you post: anything public can be copied, by anyone.
