1. Basased on the time it takes them to approve something, I have concluded that the moderators are humans who regularly eat, sleep and daven (or they are robots programmed to slow down at such times as frum Jews are likely to be eating, sleeping or davening).
2. What they ban is that which is prohibited by halacha or minhag, e.g. the frum minhag of not discussing “intimate” matters even that halachic books do discuss these matters. They also don’t seem to like kaballah meaning they assume that many users of YWN are other than Bnei Torah, or that the moderators have yeshivish rather than hasidic biases or at least don’t want to offend yeshivsh users,
