Just my 2 cents

I reviewd my raw video which where the base for DomentioN ban and apeal. Sadly i could not find something of Sniperhein1967 other then that he was killed by DomentioN with the XD-1.
I think Snipperhein1967 made the same mistake as DomentioN by picking up a weapon and use it.

This TheFlerffyBurr caused a lot more trouble then only ruining the game.

Bumped into this  ban apeal and reviewed the rest of the recording to see if it was plausible DomenetioN was not cheating but picked up the weapon.
I think he indeed picked it up.

During the slow mo you see first the hacker TheFlerffyBurr being killed. Next DomenetioN pickup the rail gun. At the end you see DomenetioN walking away with a blue laser on his gun, indicating it is the railgun.

Smarter thing to do was not to use the strange weapons, but yea can you know after 59 hours of game play.
