walls that aren't completely blatant require much more evidence and often context to be sure. everything i see in these demos can be explained by either radar or footsteps. the second demo was the most fishy but something that short...on that map, where you can almost be sure there's always gonna be someone on those sides, you need a lot more evidence. if i was to vote solely on the evidence presented, i'd vote unban, though i'd be glad to come back and watch the full map later today.
edit again: you really should've pulled that sourcetv demo to begin with. super obvious from round 1. walls.
