From Chillpoint Wiki

Any attempt to evade a ban will result in a permanent ban. If you have a brother or a friend who play on the same IP as you they are not allowed to play either, or it is considered ban evading as well.

If you were temporarily banned wait until the ban expires before attempting to enter the server.

Your IP changing is not an excuse to ban evade. If you have received no official word that you have been unbanned, then you are still banned.

Withholding information about ban-evaders

If you know someone has been banned and is ban-evading, and you fail to tell admins about this then you will be banned as well if you are caught lying to protect them.
