Thibs,
I realize this is not your idea, but I'm going to speak to you directly in the event you're considering it. Chat moderation is a slippery slope. Anytime you start talking about mods and censure, you risk losing focus on what's important -- a badass chess site. Don't worry about what people say regardless of its nature. You're not responsible for it and in no way should you busy yourself with its insignificance. Users can find a group or groups they like and stay in those circles for stimulating conversation with like-minded players.
Does anyone use
freechess.org/? The mods there are obnoxious, intolerant a-holes. I loathe that site. Lichess doesn't need that. A Mod is a gatekeeper with an inflated sense of importance. In my opinion, you need mods to mod the mods and more mods to mod the mods modding the mods... It's a ridiculous idea.
This site is great even with the jewkillers and rednecks and Chess Champions of the World (and noisivelet's) littering the chat forums with hatred and nonsense and irreverent prattle.
"an anon" is right when he says that the worst thing you can do to a troll is ignore them. Their sole purpose is to get attention and provoke you. Ignore them, and they die.
But everyone who denounces racism, hatred, or bigotry of any kind is right that it has no place here. Unfortunately, that's like saying stinky farts have no place in the atmosphere. Whatchoo gonna do bout it, huh?
Peace out, niggas.
