I've reviewed both demos without removing the smoke.  I forgot the command to do that, or if it even existed.  Although suspicious, I don't see anything clear here.  Even though he was shooting through smoke, he would spend his whole clip.  On second thought, he would spend his whole clip every time he saw an enemy.

After reviewing the demo with r_drawothermodels 2 on, and viewing his behavior, it is as if he was a newbie using wall hacking and no-smoke.  However, I would personally need more evidence to recommend a ban.  I stand at only about 60% sure right now, with the evidence provided.

To save others some time, here are his stats http://wls.gameme.com/search?q=STEAM_0% ... l&x=19&y=8
