Well, if you can demonstrate it was an accident, you wouldn't be facing the banhammer in the first place, would you?
Out of curiosity, isn't there a difference between avoiding confrontation with VIP, admins, etc, and evading a ban - as in, leaving the server in the middle of a votekick, voteban?
Actually, I think they are the same thing if they leave due to the fact they would receive punishment if they had stayed.
