Get GS involved with this, if he/she hacked into Thunders name...wait...a...minute...what if he posted?...while under Thunders name! You could find out a time slot for when he was under your name and for how long!
Then when you find the b****** call the cops...even better, send some Interplay agents after him...
*Future timeline, Hackers house*
*Hacker: "Alrighty, let's see what's happening in the white house!"
*Knocking at the Door*
*Hacker: "F*** OFF I'M BUSY HERE!"
*Door is smashed down, Interplay agents swarm into the house and surround the Hacker*
*Interplay Agent 413: "You have violated protocol number 744-931 "Invasion of Hard Light Productions Forum God Thunders Login". The sentence is death by HoJ.
*Thunder steps into the circle, many HLPers are seen in the background cracking knuckles and checking to see if their flamers still work*
*Thunder raises his HLP Hammer Of Justice, and brings it crashing down onto the Hacker*
*Hacker: AAAAAAARRRRRRRGGGGGGHHHHHHHH.....NOOOOOOOOOoooooooo!!!!!!!!
*A blinding light emits from where the Hammer hit the Hacker*
*As the light subsides, nothing but a smoldering pile of ashes is left of the Hacker*
*Thunder: "Ok, Now let's go and leave the "rest" of him to the Agents"
*The HLPers leave, and the Interplay Agents suck the ashes into a dirt devil and leave the house too*
*As they get into their black BMWs, the Hackers house Implodes into nothing*
*Interplay Agent 413: "Mission successful"
Ah....If only that could happen in real life....
