you might consider https://xbooru.com ,
it probably accepts most of what you'd expect -- anime art, western art, 3d art, sfw, nsfw, furries, low-quality junk, third-party edits, screenshots, etc.
though it still has some limitations -- no loli/shota, no real-life/photography, no bestiality; not sure about paid-rewards; i'd suggest looking through the pinned forum threads before posting anything
