Then these are the people you report. These people are not exclusive to RP servers.
There are going to be trolls everywhere and on any server you go to, you find these people in literally every game now.
Their mere existence isn’t an excuse to kill everyone else’s fun just because these one off trolls try to do the same. Report them, have the guild or rp group you’re with report them, utilize the CS forums or GM tickets for ongoing harassment.
