The client has stopped letting me block toxic players.

I am tired of the high amount of toxic players that for no reason the cilent won't allow me to mute and block. I shouldn't have to listen to toxic players and if an option to mute them is implamited then why can I not use it? I will not deal with toxic community and if the problem continues then I will just leave games and not even care. I will absolutly not torelate this crap.
