UNFORTUNATELY the destiny community is almost as bad as the league of legends community. Also. Your friend started a stream: he needs to know there's going to be stuff like that. Hell there's worse. Tell your friend to YouTube streamers getting swatted. He'll thank you. And if he can't handle a little smack talk. I don't think he should have a stream. Really he doesn't need one. He clearly has encouraging friends like yourself and the rest of the fire team to play with: that should be good enough.
