That is not true. I had a pretty long back and forth with the mods a little while back, and I thought they were going to work with me in good faith. They basically said what you're saying here: They can't read every comment, and need to report comments.

And they haven't followed through. One even scolded me for asking for proof that a certain marginalized group was violent. So it's not even that I don't believe they aren't doing enough; I'm saying they aren't willing to address it at all.

Sure, they'll remove comments were the reactionary trolls tip toe into harassment, but the mods are perfectly happy to see misinformation spread on the sub because the simple fact of the matter is they agree with it.
