1- If you don't want this to happen then put a time limit on the window so it goes away after 20 seconds, until then i can use it whenever i want
2-3 this get's tricky, when are you allowed to tell someone when they can and cannot connect to a server, they're not avoiding a mute, they're simply leaving, then coming back. unless they admit what they're doing, trying to prove it is impossible, all they would have to say is they were trying to get into another server but couldn't so they came back.
4- that should be along the same lines as communicating and ghosting with a friend. should this also apply to someone trying to jump on a nade or get tk'd so they can slay someone?
