Don't have a demo because I haven't seen him play for a bit, but I recognize both names and remember having the same suspicions. The sketchiest part about it is when confronted, he'd go spec for a round or two and when he returned, he wasn't getting nearly as many kills. This happened on a couple occasions so it kind of confirmed it for me. Like I said I don't have a demo either so this is really just more hearsay.
