I'll start by saying that i'm sorry because there is some post already talking about that but there is no improvement and wanted to talk about this feature that is utterly useless as it is right now and has been for years.

So restrict mode inform the viewers that his message is not being posted, this is the problem (if possible i would like to know why it's made like that), because every time that happens, the viewer will start saying problematic things or spam, or it should be used to check if the users is correct to continue chatting. Please remove the inform message and just make it more like a shadowban.

I also have someone that keep doing alt account to avoid a ban, every time we ban an account he starts DMing every mod and then make another account. The restrict could be used to make post message that no one could see and avoid the alt account problem or at least reduce it.
