For their support employees it might sound enough for unban the account if you're caught botting this weekend or so, but technically speaking is kinda hardcore to decrypt the passwords the way they are stored. Far different from Microsoft and Sony's PSN whom stored the passes into raw files mostly without encryption, Blizzard always cared about security due the high-lvl of breaks-in into accounts to steal items and gold.
Do not exaggerate on your botting actions, otherwise you can draw attention from whom who is responsible to report you, the other players and GMs.
Play safe, play long.
