I also did in my instance at federotica.com
Porn and gore don't really work well together in my experience. Gore sites often attract "free speech" folks i.e. nazis, redneck racists, antisemites, homophobes, edgelords etc.
Unfortunately those are also the most active users on gore sites. If you really want to run a porn or nsfw site you're better off not allowing them. I know the decision is already done (luckily) but there are good reasons you shouldn't allow them. Sites that allow complete "free speech" devolve into a trash site that just posts noise (look at efukt or 4chan).
