There are sites like gurobooru where stuff like this gets posted in gallery as opposed to imageboard format, but most of anything that gets posted there will come through here, there just isn't anywhere else that's 100% English speaking with the population gurochan has.
Personally I always keep an eye on the new results for guro and peril on e-hentai and occasionally deviantart for less bloody stuff.
Your best bet is to find a particular artist you like, find where they upload their stuff and just follow that.
