PSA: Make your alt accounts in advance. Do not make them soon after being banned.

This advice definitely wont reach those who aren't affected, but if you've been banned and you've been rebuilding your account, PLEASE make another alt in advance, so that it can be used without under suspicion of being ban evasion.

That way, if the unfortunate event happens a second time, you have another account ready (preferrably archived with friend list names and server invites and all that jazz).
