Is not a big deal to get unbanned but your story doesnt fit. You said you quickly unplugged the power but actually you closed the game first.
02:01 [All] Loco^Is^Stoned has left the game voluntarily, Loco^Is^Stoned was autobanned.
You will probably get unbanned but keep in mind that being honest in your un-/ban requests will get you better results. (in case of power failure the exit info should suggest that you were dropped by vote or unrecoverably dropped by gproxy due to xpam process' death)
