Mbin has multiple options to deal with problematic users:
- Ban the user -> federated to other instances, user cannot login anymore
- Suspend the user -> not federated, user can still login, but not create any content
- Delete the user -> federated, the user and their content is deleted
What should happen with the content of a banned user? Lemmy still shows it, but puts a “Banned” badge next to the username.
lemmy (1.0, not yet live) will allow banned to users to delete their accounts themselves: https://github.com/LemmyNet/lemmy/pull/5643
