I'm speaking as a gamer right now, not as a streamer or Mentor or anything else. I'm also not going to take sides, just share my opinion. When it comes to streaming, private property/IPs, and anything similar to those (YouTube, a forum, etc) the creator has the right to silence whomever they please. They have the right to filter their feed as they want without a given reason. You could say "You have nice eyes" and they could permanently ban you for that. Why? Because they can. If they feel antagonised by a viewer, there's no reason for them not to block that viewer. I don't think it's a matter of being sensitive, which isn't a bad thing, but wanting to cut out as much hate as possible, since they receive a lot. It's easier to block it out than to have to deal with it one way or another.
