i got an f1 for mass rdm at server 2 spawn, went there and the guy killed me and killed everyone at spawn... froze him and warned him for mass rdm, kicked him... he kept coming back and trolling etc... i just had to keep warning him till the 3rd one where he got automatically kicked but he never rejoined the server that day, i had to make a post on the forums to get him banned... plus in the time i had to type the freeze command he was able to kill a couple more people
