This would change everything offcourse, but it would be really hard to proof blackmailing unless h4ns could confirm this.
There are some other users I have mentioned in my last post can confirm such thing. May be a fear from h4ns has forced him (h4ns) to drop the claim.
If h4ns is being blackmailed, i'd encourage him to go to his local law enforcement agency and open a case against GP, then come to the forum with this case. Theymos has ip logs, there are payment traces, GP has an active website and claims to have defended cases. I'm pretty sure a serious law enforcement agence would be able to trace him in case somebody opened a police report against him.
The idea is good and off course theymos has the IP logs but question is if he will share it or not. If he does not then things will go worse for h4ns. And from practical experience I never seen theymos to step in to this sorts of case.
