My contribution is somewhere on their website, but my name is attached to it and I don't want some rabid DUer to wake up some morning, drink an extra mug of crazy, and decide to kidnap a Freeper for kicks.
I could probably handle being tied up and beaten, but what if they made me look at naked pictures of the Code Pinkos?
But just think how valuable that experience will be when you need material for your next novel!
