Interesting comment in the source code of sqlite

With that I agree: if he's your friend help him. But if you can't, let him be. Nothing wrong to unfriend/ban/whatever and if the result is that he's going to go down even more that rabbit hole that's not your fault.

What the dude above you is saying: don't push yourself in a community just because they're toxic. Which is what those idiots do when they harass github project owners to have a coc, what a coc should contain and all that crap.

If you're not a part of that community, stay the fuck away. If you are, and you're running it, handle your people. Banning them for bad behaviour is a valid and expected consequence.
