Ban = delete account???

Hi, i got banned some months ago with alot of different accounts, it was on molten wow but might help to post anyways.
well i got banned for hacking, my friend told me to download it and do like he did to reach something.
we got banned and after that i havent play on some months now when i try to login it says "invalid password" wtf?!
i remember i had a boosted dk and boosted warrior on that account cant remember much more, cant remember the name either was some months ago been playing alot of different games since my ban is there anyway i can get it back?

it was before wipe or after that? because after that everything got deleted twice and everyone had to start over.
