Attached Link: What is the problem?

I made a model of, Kimberly Holland, Playboy's Miss October 2004. I rendered an image. I sent the image to Kimberly, asking if it was okay to use it. I also asked her if I could use some of her personal snapthots. She affirmed to both. I contacted Justin Zucker of Playboy, he tells me there's no problem with Playboy on either issue, just so long as I'm not using their photos. I'm not. So I post the image. Suddenly I start getting messages from the admins: We need a signed release You can't have a link to a site that has porno links on it So, I give the admins the contact info of both Zucker and Holland. Now, I'm linking to Kimberly Holland's yahoo group. It has links that take you inside the Playboy Cyberclub (you have to be a member to see them). Those are porn links? Hello? Hippocracy!!! This site has images of naked children on it and all kinds of S&M paraphenlalia being sold for people's artwork and suddenly Playboy is porn? And there's a render of a model of Angelina Jolie posting just hours before MY IMAGE! Do they have a model release for THAT ONE? (Yes, I had to have permission to use the figure too! It's kimberly's likeness. I have it, Renderosity refuses to confirm it). Bottom line is this: I want to know the real why Renderosity is so opposed to this image.
