Deplatforming means removing a user, group, or organization's access to a platform, permanently or for a long period. It's the strongest enforcement action, usually reserved for serious or repeated violations.

‍

‍Why it matters

It sits at the end of a graduated system that starts with warnings and temporary restrictions. Some severe violations skip the ladder entirely. It's also the most contested action, because it ends someone's ability to use the service. That puts pressure on platforms to apply it consistently, document the reasons, and offer an appeal. It's different from shadowbanning, where reach is quietly reduced but the account stays.

‍

‍How the decision gets made

Many platforms require a written record of the violations and the evidence, and a second reviewer for high-impact cases, such as large accounts. The decision is checked against the policy that was in force at the time, then communicated to the user along with how to appeal.

‍Ban evasion

A ban only works if it holds. People banned from a platform often return with new accounts, so teams look for signals that connect a new account to a banned one, such as behavior patterns or technical details. Evasion is usually treated as a violation in its own right.
