I’ve commented there on a /news community with sourced points to make my argument and was basically told to shut the F up and had my comments deleted.
So I blocked the community.
I’m not sure how to deal with extremist mods any other way. Their instance, their community, and other than defederating and putting a lot of effort into restarting and growing any valuable communities on another instance while keeping the undesirable .ml gang out, I’m not sure there is any other solution.
