what i see is jerky mouse movements. it's not consistent with aimbot from what i've seen though. 2 things about this, it doesn't snap to any particular thing (it's usually torso/head, and here it's nothing). there's also no parkinsons, i.e. no shake. it's just a jerk one way or another. also it doesn't help his aim any from what i can see. the most interesting tick is 39-40k, especially 40k, where his crosshair moves onto the ground, shoots a bullet there, and then goes right back to the target he was shooting at. normally i'd attribute a movement like that to some kind of a source engine bug, but since the bullet he fired went into the ground right where he was aiming, and then his crosshair snapped back up...i dunno. but that's really the only serious wtf i see. when it comes to regulars with very few serious wtf ticks, i'd like to see some more consistency with it before i made a ban myself.
as far as outside the demo goes, i can't find any other steamids linked to him via ip, but he only has 200 hours in css, over half of which are on our wcs server. his account was only activated at the end of january. that's fishy to me given his 1.63 kdr...but like i said i can't link anything else to him.
overall, i'd like to see more consistency. there was one tick that has me really scratching my head, but i'd rather that be part of a body of evidence rather than standalone. my vote would be no ban, for now.
