Yes, there is no doubt about that. I had to register just to check this out. All players registered at the same time (a month ago) and all use their full name (sometimes even their title), although this is not required at all when registering a new account. Also, if you check the "Biggest wins" or "Biggest losses" list, all the games were played at the same time, also a month ago. You can't get more fake than this!
