Seems right now that Freek aka TheNerd was hijacked.
It's bullstuff. Let me tell you why.
So, first, he goes into the thread and gives it enough time to get some replies, and a quote comes up with the post saved. No reason why he would do this if he was instantly notified about the thread's posting.
And then, what happened, is that he didn't lock the thread or email a moderator or admin about the situation (which is the first instinct of what to do when you're hacked.)
The hacker also appears to be doing nothing else to his account, not changing anything. He just posted the thread, and the hacker was gone. I seriously doubt any real hacker would just quit after posting the thread.
He's acting too much like someone was hacked. I'm not saying that like, to be stupid, but he's just being that guy. He's freaking out when he obviously knows that the posting of the thread was the only problem.
His entire profile is safe and there is nothing that has been changed.
