I made a demo, after i asked this guy to stop laming on w00t. so its short. but he just stays in base on w00t to frag. he leaves, but comes back in the game after a couple of minutes and does the same. (and as said before, before the demo he also did dm)
of course this was a game of nothing, unequal teams and I switched back to red and blue a couple of times to even it out, since no one bothered. but laming is laming imo..
