>>618452d gore is very much tolerated on /b/.
Just like 2d gay porn.
It's the 3d shit that is a problem and isn't tolerated.
Though I do admit it took the mods way too long to put a stop to people posting gosky and fetish spanking porn that had buttholes and genital in them. But that was a couple of years ago and they are consistent with deleting that stuff now.
