I think as long as Piratez is vague about how depraved the pirates actually are as well as other factions, it's going to continue to be acceptable. And I imagine it's not going to stop being vague since that bit is very much player headcannon and player action rather than lore.
It's not a bad site, I just roll my eyes and sigh at them every once in a while. I'm from the States, and part of a culture that is generally seen as prudish, and I think they put too much emphasis on protecting people from sexual things, and not enough on violence.
However, it looks like Steam is planning on relaxing their rules regarding censorship, though I guess that's very of subject.
