To anyone who has doubts, I would urge: just go and read
the announcement thread for Anastronaut. Now keep in mind that all the first few posts from AnasAbdin, Kimbra, PassionatePatty and redMatter were made from the same IP. That means they were probably written from the same computer, and certainly from the same room (given plausible setups of a university computer lab). Now consider that after
the post by Ascovel (i.e. a while later), the next bunch of posts by AnasAbdin, PassionatePatty, ~TongueSplit~ and MattKatela were also all written from the same IP, different from the first one (posted from late afternoon to late night, and the following morning on a non-workday).
Do they read as if they're written from a bunch of students to their teacher while they're all sitting next to each other in the same room, making no attempt to hide this fact? Is it plausible that they could do this while being completely unaware of each other, even when the messages are posted only a couple of minutes apart? Would the teacher's only clue be the photo of one of the computers? Would you believe that a few hours later, the same thing happens again from a different IP? AnasAbdin would have us believe that wherever he goes, all hours of the day and night, he's stalked by a group of up to a dozen student fans, who log on to computers right behind his back in order to praise him on the AGS forums without his knowledge. It simply is not credible.
Even before we named any names, without knowing anything about the IPs, people were able to point fingers; because once you look at that thread, it's obvious that something fishy was going on.
I live with my brother and he has an account here. I don't believe he's logged on in a year or so though.

Mentioning it just in case it had come to your attention in your identical IP hunt. We're twins and since we have the same birthday on the accounts is why I worried you'd think it was a terrible attempt at a sock puppet. 
Ah, the old "evil twin" excuse!

Thanks for the heads up, Ryan. This is the kind of thing we'd like people to disclose (to the moderators, at least, if they don't want it public).
