He didn't bribe him. Yawgmoth is one of Chruser's friends outside the walls of the internet, and Yawgmoth thought that he could be of some assistance to this forum. Of course, the whole 'you're doing everything wrong and my way is right because I'm an asshat' act was completely uncalled for. I think he did mean to be serious, he is just plagued by guilt because people aren't taking his posts as 'jokes' when it's an obvious coverup on his part. My guess is that Yawgmoth would not have this position if he did not know Chruser, because he's a power hungry prick who cannot agree with anyone but the likes of himself.
