It should mute text chat too…
It should, if you mute someone; you obviously don’t want to hear from them.
There should be a separate option for squelching text, but I agree that it should be there.
Leave it as an option to keep the text, in case you’re just trying to mute a music spammer or something.
I assume a raging hate spamming lunatic using microphone to troll people and feel better about himself should be able to be squelched across all mediums. Sadly, there’s nothing to stop people from throwing matches by being counter-productive.
