They're probably not afraid as much as trying to create buzz. Wasn't it Burger King that had the website with the guy in the chicken suit that did anything you told him? They didn't link to that one either if I remember.
Saw this page on the national news this morning. All the "it's porn" hype is pretty silly IMO. Wouldn't be surprise if the Gap itself started that frenzy to add to the hype. Checked out the site. . .Let's just say that if you want to get off on porn there are much more efficient places to do it
