Ok, I did some google hacking and found him:
http://74.125.113.132/search?q=cache:qi ... clnk&gl=us
Looks like he changed his name to:
http://avatars.imvu.com/metsulanxxxxxx
Here is his name change log, which will let you keep track of all of his name changes:

ASL: 33, Male, Canada
The only problem is, disabling a h4c|<7r will not prevent them from hacking you. When a h4c|<7r is disabled...he does not just lay down, he gets pissed and h4c|<s you even harder.
I think what we need to do is focusing of securing your account, so he can not h4c|< you. Would you mind PM-ing me your account name?
