Not sure what you guy's guidelines are as far as glitching goes. To this day I can't decide if he is using an invisibility hack in this round and he decided to not use it again or if there's a glitch in Pearl Market I am not aware of. Either way, these are a spectator videos recorded by someone else and you can see the playerdoing some funky stuff.
That one is definitely a glitch as the entire playermodel is straight up gone. Hacks don't/can't render the weapon model invisible.
We currently have no glitching policy but will most likely try to work one out in the near future.
