On an Ajax-forum there was a guy active who calls himself Blackmoon. He's always on vacation in Thailand, so he can't immediately respond to other poster's questions about his vague rumours, but he has inside contacts because he does business with someone high at the club. Of course this guy can't give away full details to Blackmoon, so he only knows some stuff and he can't mention everything immediately on the internet to not bring his insider into trouble.
When he first started he blew up the forum, since within a week he had topics explode to over 100 pages (a bit like our Davis-thread, only than within a couple of days). It took a longtime before everyone was aware that he was a fraud. I just looked him up on google and apparently he's still active trolling football fans.
