@NobodyReally I'm not just referencing this specific issue. The point is that these sort of things never end at 1. The way that moralistic things snowball is good intentions gone astray. You create a rule stating that streamers are not allowed to suggest their opponents might be cheating because somebody took offense to this. Okay, whatever.
Now suddenly another streamer makes an off color joke regarding his opponent. And now another stream watcher comes up here, "I was watching this stream with my 7 year old son and he said 'x'! What? You're not allowed to say your opponent might be cheating but you can say 'x'? This is ridiculous!!! Fix this or I'm leaving the site!"
You have to draw a line somewhere, but the problem is each time you push that line forward it gets easier and easier to push it even a little bit more forward. This is how you get from dressing modestly to covering yourself head to toe in opaque black.
When you look at each little step on the way there nothing ever seems like a big deal. It's like if I ask you if you pluck out one hair from a full head of hair. Is that person bald? No of course not. How about 2, 3, 4, 5? Exactly how many hairs do you have to pluck before he is bald? From any given snapshot in team it never seems like he becomes bald does yet taken as a whole he most certainly does. So I take the stance that we shouldn't begin plucking those hairs in the first place.
So long as there are sufficient means to handle things on your own (such as blocking) let people be adults and decide for themselves what is or is not appropriate. The only exception would be for obviously majorly and intentionally disruptive things - spam, overt attempts to disrupt "normal" forum activity, etc.
