3dcg really needs some new moderators, shit like that should and could be deleted instantly yet it takes whole days and make the whole ambient toxic, btw worry not that image is not illegal it is taken from a random bdsm movie

if you really feel like migrating somewhere else tho i suggest just creating discord server so you can moderate it yourself (is not like there's gonna be 1k+ people) and easily share your works, pixiv is also good, can't think of any other platform that would allow you to upload guro material undisturbed
