I am curious, how did he get to you?, the mentioned thread was posted yesterday, so there is no way to have "talked to this guy on skype for a cpl days" from there.
People have confirmed the signed messages so I guess your claims are true, what did he tell to you?, I also contacted him via PM and the offer simply seemed too unrealistic (In fact, I posted in the reputation section about that, Cyrus later moved my thread to Scam Accusations). You also called some guys "delusional" because "most sites moderators earn 0" here, I know admin and mod are not the same, but they are close.
Wait, you were looking for unpaid mods for your site yet you were applying for a paid position?, I admire your double standards!, specially considering I have read a couple of posts from you criticizing people's greediness (apart from this which I have no idea if is you or the hacker, this, this, and probably some more, I am not your personal biographer...).
Just because the messages are confirmed does not mean anything, this guy is playing games as much as the guy that he is claiming did something to him. It is all just a big game and everyone is jumping right in and helping him, the timeline does not gel and the story does not work with the messages, have fun guys!
