nudity/ porn: what's allowed to be linked?

[Smell The Glove]

What's 2p2's policy on how filthy a linked image can be? I'm not talking about inline pictures (especially since the policy on that seems to vary between forums). It's my understanding that 2p2 has a policy against linking to images of "hardcore" porn.... OK I guess I don't really know what's meant by hardcore. Obviously really sick stuff like bestiality, etc.... and penetration is probably included in that. In bbv4l Dids' inline porn rule applies to all nudity (even paintings of Mary Magdalene). I'm pretty sure that linking to a picture of a Playboy-type nude image is OK, since I've seen it done on 2p2 a million times. I guess I'm just wondering how far that policy extends.

I pm'ed Dids about this the other day, but haven't gotten a response yet. Specifically what I was asking him about was whether it was OK to post an image of a naked woman, who was tied up, and another woman was touching her vagina. It wasn't all close up and nasty or anything... it was a long shot and pretty tasteful imo. (This was in the context of a thread on the appreciation of "robust women," btw.)

Any clarification on what's allowed and not allowed to be linked would be fantastic. oh yeah, also I should note that the image links would include NSFW tags, obviously.
