Some people handle the trash talking well some don't. I don;t think it's healthy for the game to have everyone see it scrolling across the screen all the time. It just creates so much negative noise for the people that don't want to read it. Perhaps default radio setting would have 200 de-tuned. '.P' messages should come with an out of the way menu box that asks if you want to receive a private message from so-and-so, with option buttons to Mute. If muted you get no more pop ups. Making it easier to mute people might help. Perhaps right clicking on a message in the radio buffer lets you mute the sender.
In the end we should all be more immune to the rantings of aggravated players, but everyone has their limit for dishing and receiving. Some of these change might push that limit out a few hours.
