I didn't get to spectate him when he played on Panda servers because I already knew he was a hacker from spectating him previously on other servers, so I don't currently have first person evidence of him playing with hacks on Panda specifically.
Why would he get away with it if he only uses hacks outside the Panda servers? he's a hacker and shouldn't get the chance to play in any servers because you never know when he decids to turn them on without anyone realizing it. I've seen so many people think he is just "too good" but no one took their time to spectate him, he knows where everyone is behind walls and instantly headshots them when he peeks, Plus he's probably abusing some cl_interp setting that makes all of his stabs really weird. he can backstab people when he's clearly in front of them.
If I had the chance to go through the demofile of the Panda server I wouldn't have any issues to get footage of him using these hacks, but I don't know if it's possible to view the demofile for non-admins.
