It's pretty simple. Myers was suspected by several people to be using Quix as a multi account based on skill and play style. Cheating was detected on both accounts (same cheat). Myers was banned for cheating, but it was still up in the air as to whether it should be an additional 16 days for a multi or a separate cheating ban for Quix. Myers had a bunch of excuses to disassociate himself from Quix (Quix played at a friend's house, there were no demos of Quix playing on his computer, etc.). The case went unresolved, and Quix mysteriously ceased to play completely. There were lots of other suspicious things, too (Myers' email was registered to the Quix account, for example), but Myers always had excuses.
When the issue was brought up yet again on the forums recently, I thought, "Screw it, I'll just ban Quix." Quix doesn't play anymore, so that shouldn't be a big deal. If Myers was honest about Quix not playing on his computer, then there should be no issue. All I banned was the IP and hardware from when Quix was detected cheating. Of course, it ended up being on Myers' computer.
Maybe somebody still has some demos with Quix playing and we can resolve this once and for all. It would have been around January 2009. Just search your demos directory for files containing "quix". If you have Windows 7, the search is completely broken, so you can use this command line tool:
start|cmd
c:\
cd \games\paintball2
findstr /i /s /l /m /c:"quix" *.dm2
Not sure if that works in XP. XP had a pretty crappy search tool, too, so you might just want to download some kind of find in files program.
