No amount of rework will save any kind of forum. The biggest virtue of the internet is freedom of speech, accessibility, anonymity. This means anyone can put a statement, regardless of the quality and viability of said statement, and said statement will find some traction regardless.
You cant do anything about that without destroying the internet in the process. The solution this forum has is to censor words by banning people, do you think this has done anything to alleviate situations where individuals reach the breaking point? No it hasnt.

To put a direct comparison to the salt mines game. Do you think a guy in League who keeps swearing, blames others for his mistakes is any different than a guy in here who goes dont tell me how to play regardless of the pleas of 3 or 7 other people?
Both just dont give an ounce of deep frying shit about their team. All that the strict ToS has done is give them a leeway to scream harassment whenever they want to whoever they want.
In Fact im gonna go ahead and say this community is more prejudged towards mentors and raiders than League of legends is racist to each other.
