If Ты were to be suspended how long would Ты be suspended and how would Ты know when your suspension over?

If a user is suspended, they would, most likely, be suspended until the end of time.

People have not been getting suspended for no reason. When a person reports a user for something it doesn't usually result in a suspension. The F4 would have a look at it and do what they see fit. If Ты were suspended - it was probably for a fair reason.
