In viewtopic.php?f=7&t=292111, Celter is probably using at least two puppets to agree with himself to make it look like more people agree with him. The three accounts mentioned all begin with C, all were created within a day of eachother, and all get logged into around the same time judging by the online banner, but never at the same time. Celter claims they're his "friends" but several of his (and his "friends'" claims are inconsistent with each other. He previously used a different puppet to support himself in another thread. Another user expressed concern that Vankelland Islands was also Celter, but I'm not sure if that's the case. Crugscangel and Cyrumstron seem pretty obvious, though. Neither of them have any posts except in that thread.
Edit: Vallekland Islands and Celter are both in the WA, so if they are, in fact, the same person, we also have WA multi-ing going on. As I said, it wasn't me who was suspicious of Vallekland Islands, it was another user. I'm just repeating their concerns here for the sake of being comprehensive.
