I've asked Snopes twice now to debunk the "Ann Coulter is a man" thing that the DUers keep trying to spread. Not even a reply from their editors. She's a big, controversial public figure, so you'd think she's be worth the time. Not for Snopes, though. Can't help but wonder if they like that nasty accusation floating around out there.
They did use the spoof photo of Kerry together with Jane Fonda to taint the real photo of Kerry together with Jane Fonda.
And I seriously doubt they ever paid Corbis to license the photos for use on their site (in part because Corbis DOES NOT own the license to the spoof photo, that belongs to some prankster who was likely a FReeper even though he does not own the license to the actual images that make it up, as a digital creation and in the absence of a court ruling giving Corbis the rights, they are not to be licensed, plus Corbis would be unlikely to license such a hoax). Meanwhile Corbis prohibits FR from even using a URL reference to post even the valid pictures.
I was the one who tipped off Corbis' lawyers to Snopes illegal hosting of the images (real and hoax) and Snopes only response to was add a copyright credit. The left look out for their own, apparently.
