Contact VSTF and Staff at the links I gave you. They can help you out. You can undo image changes in the file history, just click the "revert" button in the left column. Staff can rangeblock IPs, prevent account creation and lock image replacing, and probably have more options they can discuss with you at Special:Contact/general.

In the mean time, no matter how bad and miserable this guy is, still, do not feed him. Though judging from past activity, he's been fed for too long already and this may not help anymore. But don't do it anyway.
