I got 4 demos of somebody haxing. He used about 5 different names. Names (all same person, since the score was "logged" from when he left and came back, either by votekick or by user disconnect):
Cotton-Eye-Joe (I think that's how he had it)
scubasteve (I have at least one demo with him under this name)
æææææææææ (something like that, at least one demo with that name)
æææææææCOCKkæææææææ (same as above, not sure how many of the æ's he had in those names)
QQ?
Screenshot (he's the one at the top, he got up to about 80 before he left the server [I had already disconnected at that time, but was still keeping an eye on him through the Xfire server list and what somebody was telling me through xfire]):

Demos (Pack of 4, unpack with WinRAR; not sure if needed, but I did them anyway):
