@adamdavidson I can recommend you block social.076.ne.jp and video.076.ne.jp (or just wildcard block it), as well as block aaaa.moe, iiii.moe, uuuu.moe, eeee.moe, and oooo.moe in advance (they're not launched yet, but these are all maintained by the same people).
These instances are all anarcho-free speech, littered with lolicon drawings, there are absolutely no rules against copyright (which is a scam), free speech (including hate speech and other insults), ismphobia, and so on, because it's each individual user's own responsibility to block or mute whoever they don't want to talk to.
And all reports against any of these get dismissed immediately.
