I find it strange someone would use a stolen account to buy hosting. I mean, how long to they expect it to be up for before it gets taken down and investigated?
revenge? i think the best thing to do, if you haven't already is to report the issue, get your money back, let the authorities investigate, lick your wounds and be smarter next time.
Why waste time trying to get revenge when you can be wasting your time making a profit of some sort
