Well you can't say no one else has been suspended for false reports, because we literally don't know and can't know whether that's the case. However, Blizz have said straight up it is something they do, even from before that particular furore.
I don't care about trash talking and insulting people, as long as it's kept personal; that seems very much the stance Blizzard are taking with this. You cross a line when you start bringing sexuality, gender, race or whatever expansion to a collective you want into it. You make it about more than the individual feud at that point, and that is what people need to learn. That that is not okay.
I'm sick of seeing people pretending they're victims because they think they can't participate in trash talk or insult people, when its very evident from Muma and Nico that actually, you can. You can insult people and trash talk, and get away with it just so long as you're keeping it between yourselves.
If you lack the vocabulary and mental discipline to stick to that language without resorting to bigoted insults that demean people who have no involvement, then that's entirely on you to fix. And you can fix it. Unless you genuinely believe that those groups are below you, then we have a very real problem.
