@LYTE I KNOW HOW TO REDUCE TOXICITY. Probably been suggested before.
Just add a squelch option next to the mute button... If you don't know about it, squelching stops the squelchee from hearing you... if you just squelch as crap player who's pissing you off, you can talk all the shit in the world to them, and they'll never hear it. You, as a behavior "specialist" should know that venting is the #1 way to relieve stress and frustration.
