As I said it is not about one isolated case of one guy annoying a streamer or a new player it is the fact that unlike anywhere else these behaviors are tolerated.
It is quite easy to see when someone cross the line one ss and you have your nasty comment immortalized pretty much.
The thing is people are less likely to say nasty things that don't belong there if they know they can get banned for it in the first place.
Most of the time these people would never say something like that anywhere else for that exact reason.
I am a new player I log in I see heated and full of hatred racist and antisemitic talk on the general chat what do you think most people's next move is?
Its always the same with rules rules can be considered as limiting one's freedom true they also make sure that one person's action wont ruin other's experience.
Again It is about having a welcoming environment for new people.
About strengthening the community as a whole and providing an environment that is healthy for gaming and fun and where people
feel safe to stay and even let their kid play.
I mean it is quite simple to do the link a lot of people came to my stream chat saying the community is horrible, I say it is time we do something about that.
Why should we tolerate a few disgusting members to have such a bad impact and draw such a nasty image of our community.
Imagine if other platforms like steam had no terms of use on their community's pages and all.
The problem is they are not just flagging themselves we all pay the price of these behaviors.
Its not about banning more people its about providing a set of rules that will eventually avoid problems to appear in the first place.
Also it is not about doing something new, Battle.net used to have terms of use.
Here is what they say on blizzard's website about harrasment:
