Okay, so Exro did definitely see you while you noclipped in. Yeah, perhaps you could have used the excuse 'panic' or 'scared' if it was a spontaneus kill, but there was voice communication going on all the time, and Exro was well aware of Liam in there with noclip.
Liam didn't really do anything wrong by noclipping to talk to you about it, despite the fact that he did indeed talk to the wrong people.
So, the only staff punishment viable here would be no more than a verbal/T1 for Exro.
Then, the following players can have a 1 day ban for RDM, which you can do yourself Liam:
STEAM_0:1:60062636 - Hunter
STEAM_0:0:36864772 - Borat
Other than that guys, this is a ban request that
by no means pertains to Liam. If you feel you have evidence of your RDM accusations, take it to your own ban request.
@Liam - you need to ban those two steamids accordingly, and lock this if you have no further evidence to hold against staff.
