AppleJuice I belive they have all seen it. It does look fishy, and in my opinion, he was AimBotting. One Fu: Member also agrees he was aimbotting, he will remain nameless.
Honestly, if you are scrimming, DO NOT play aginst people without GUID's. Honestly after the fact that about 1/4 of players own an aimbot, why do people bother letting people with names in a clan match without a GUID. First thing I always check whenever im in a server, expecially if I see clans matching.
That is my two cents.
