As controversial as it is, there are sites that can host such content, let me put an example, the Japan based DLSite web, that allows loli, furry, bestiality, guro and so, but that content has to adhere strictly to not IRL stuff and has to be censored (as by Japan's stupid censoring laws), but, on this side of the Pacific Ocean, things are a little more open, specially regarding censoring, and highly probably IRL content of such nature might have been on the site, or maybe that incest, rape, loli and so was on such high search hits on the overall searches on the page that it raised red flags, and made the higher ups to step inFor legal reasons, I totally understand their censoring methods but for the sake of creators, there must be a hierarchy in terms of what should be acceptable or not.
Incest and bestiality as long as it is pictures or in game content, why not? But the limit should be pretty well underlined to not go overboard with lolicon or awful shit like this.
