Twitter today announced a new feature that will allow users to appeal a tweet that’s in violation of Twitter’s rules directly within the Twitter app. When users post content in violation of Twitter’s guidelines, that tweet can be flagged or reported, resulting in an account suspension or lockout. Before, users would have to visit an online form to appeal Twitter’s decision.

Accounts can be suspended for a range of activity including spam, being a fake account, security risks (like hacked accounts), and abusive tweets or behavior such as sending threats or impersonating other accounts. (The latter which Twitter itself recently did as a joke. Ha ha ha. How hilarious to send 2FA codes over DM!)
