...and mute em...
that being the prefered choice, but due to not being implemented within the ingame chat, you would have to do it for every new map or server login. There is no client side perma mute for the ingame chat, even though i suggest that now for over 2 1/2 years.
For forum mutes, you still see that the arshole you muted is saying something and sometimes their shit is quoted and you are reminded of his shit and you have the option to take a peak at what he wrote ... wtf for a mute option is that?
