Don't mean to derail this thread, but how come he gets to have someone flag his hacked account, yet when my account was hacked nobody gave a shit. The worst part is that the guy who hacked my account is still using it (awesome31312) and it's so obvious he hacked it because the hacker speaks a different language. Also, the "hack" was really a vulnerability on Bitcointalk which allowed him to change the email of my account and use it like he owned it, all while not sending me an email notification. What a shitty forum.
Kenzawak's account is being red-tagged because it attempted a scam, plus the real owner signed a message. As far as I can see you couldn't prove ownership of your hacked account but I might be wrong. Did you try the recovery procedure:
