And currently the issue is that a banned user will still be able to upload illegal images.
Change email or password is not a solution as if you change the email... banned user can register a new account with that email. If you change password, banned user can reset the password.
Long time and I'm still stressed by the impossibility in Flarum to disallow login or block this avatar changing permission 🙂
There is completely no solutions seems at the moment.
