I don't think it would be good.
1st: We have a lot of people in toribash, people from the entire world, not everyone can speaks english, so they would speak in their native language, it would be pretty annoying to listen to someone ~screaming~ when you don't even know what they're saying.
2nd: People raging everywhere, calling you this, calling you that etc.
If they rage while they're typing, imagine how it would be if they were allowed to use a mic to complain.
