i thought he meant "sitting in vent" when he said venting, but then i understood he was talking about teamspeak bcos its a team..
venting/ghosting can be monitored nearly the same way we monitor radar hacks...
i agree with vlad, sometimes we can suspect it , but cant really prove it ...
most of the time they would be ALWAYS travelling in groups of 2 + obviously, and it would be players with gd reflexes when their buddy is on, but sloppy gaming when they are playing alone...
its kinda a progressive intuition...
i suspected one of that the other day... and it just turned out he was just walling :P got banned (forgot the name)
but i agree/// its hard as fuck to track those "team speak" ppl ...
