a good to thing to find lamers is to let an 1st view spectator, not only the 3rd. In 1st you can see hwo the guy plays, so if he is cheating, like an aimbot, anybody can say that he is cheating.
There is my story :
It works on q3, i was playing ra3 (ok ok ;c), and i played against a guy sigfried or something esle, so we start, and he shaft me like a very good player, so its ok, i say whoohoo nice shot, after some times il get killed (all frags..), some admin servers come to play, and so we played like 6players in 1v1. And i like seeing how a good player tend to fire strafe etc, so i looked at the sigfried..and ohhh what a surprise when i see that the guy started to shaft when the other as 1 pixel of the corpse viewable, and with killed him when jumping, all the shells on the guy.
Ok, some very good kickers pro play like hell, but not like putting all shots in a man and with ping (never see fat, or zero4, or deathb, or any cpma pro gamer with 100% of accuracy). So i talked with the others players and so one of admins, all so looked after how the men play, and at 99% he was really cheating, never diing, all shots with any weapon inside, and firing before the guy was viewable, the admin just banned him some secondes after.
So, plz devs, let an 1st viewable spectator mode and not only an 3rd like ut2k3/ut2k4 (i know its not the same). But some times we forget that human eyes are sometimes more efficient that taking screenshots or logs.
