Hi Greg,
Thanks for posting the demo. We always appreciate it when people take the time to record and post possible concerns to help keep our server running well.
That being said, in this case, I didn't see any evidence of a wall hack. He was spamming bullets everywhere and throwing random nades, not even getting hit markers in most cases. It did appear that he may have bound his trigger to the scroll wheel, which isn't allowed. We will keep an eye out for him on that issue. As far as hacks, I think he was clean in that regard.
Thanks again for taking the time to post!
Cheers!
Jock
