Well, they are a radical feminist sub that was created in opposition to /r/GenderCritical who were banning them for being even more radical than the GC feminists themselves are, so of course they're going to censor people, that's what feminists do. Remember, they too are just another flavour of SJW so control of the public discourse and censorship is in their DNA. It's interesting though that you bring them up as an example because I had once looked them up myself on Reddit to see what they were about and IIRC they seemed to have their rules very clearly stated on their side bar. Makes me wonder, why don't they just copy-paste whatever they had on Reddit here, perhaps with some changes?
