@shadow8t4 I'm not a fedi mod, but your Basic Guideline 3a might need revising. That's very culture-specific (which I only know from witnessing policy arguments on other sites, e.g. the comments on https://skeptics.stackexchange.com/questions/44479/is-this-photo-showing-a-woman-standing-in-the-nude-before-teenagers-real/) – that might not be a problem if all your users share enough culture, but in theory it might be better to write something else, instead. (I have no clue what you could replace it with, though.)
