UPDATE: Hacker managed to sell my account to some spammer 3 days ago, he already updated my profile with a different avatar and signature, as you can see

Also, he started posting crap consistenly every single day since 13th August on a basis of 2 posts / day on the following boards as you can see

Apparently he is growing in rank for later purposes, could be anything..
I would like to ask / request escalating this incident up to the extend of locking my account AvenG so no one can use it (which seems unlikely due to the fact that the Admins ignores us, but at least I try).
