i feel like there's a bit of an overreaction here. there is certainly a slight bias but it's not THAT big of a deal. generally avoid insults and trolling and most ppl should be fine.
that said i stopped reporting others for offclassing too much / permanently trolling because not only did they not get banned most of the time but some admin went around to message people about me "being obsessed" and shit when I know for a fact if I sniped 12 minutes in 3 maps in a row I'd get a week ban
