Information about suspension account in chat (reason, duration)
You can so that after the suspension of the account in the chat there is a reason for blocking the account, the time of blocking and a button to contact support.
I got banned from two streamers because of a two-strike rule breaking on one of the associated Discord servers. These kind of moderators of course flat-out rejected the appeal too and forever banned as such. Even a week or month would be better than forever. And add a way to stay subscribed and add silent support options. And read-only chat.
Permanent ban without giving a good reason should not be possible. But I can imagine noone is going to look at the reason if moderators aren’t moderated themselves.
