I think there should be two cases. One is to ban users, but to permanently ban (delete) users.
Ban users (whether permanent or temporary)
- The user is banned and cannot participate in any interaction on the forum, including but not limited to replying, posting, liking, and following others.
- On the user's profile page, "This user is banned due to violation of ******."
Permanently block (delete) users
- The user severely violates laws and other rules, giving the most severe punishment: permanently delete the account.
