This isn't enough to ban for cheating IMO.

@18:02 - Yeah this is a classic example of how turning up character sounds can give you an advantage.  He rotates to the left just as your footsteps are heard and then jumps out and kills you.

@17:30 - He had the Avril before he went into the Scorpion.  I can't tell what he saw on his screen but when he self destructed the Hellbender the Avril probably picked up the Nightshade.  He didn't hear or physically see the nightshade at firsr- I can tell you that -but he had his Avril out.

@11:55 - He could see your Manta as he was coming in.  It's faint but you are visible.  There was also dr_db in the nightshade on the flag and he went right past him.  Unfortunately dr_db didn't do shit to prevent Lesbian from scoring.

There are a few other examples where he didn't see people in this demo.  Most of the complaints I see of him cheating are early in the morning.  He becomes more of a pain when the player count is low enough.  Personally I've never seen him clear a full server.  Ban him if you want- I'm not going to try to defend Tony if you don't want him around.  I didn't ban him on MattMan sucks because I know he becomes less of a pain when more people come on the server.

This is what is seen with sounds turned up in behindview:
