Not sure it requires a ban for that but I found a bit annoying (just now) to be called a cheater from a dude that simply is not really good a quake, unfortunately.
I decided to record only after a couple minutes, basically he don't like the way I kill him and call me a cheater

Not the first time I have seens this anyway, but this was was even trying to fall in lava etc, just to avoid playing with him, instead of just spec and see me..
I let you judge,
Many thanks in advance,
Cheers'
