What if your name was John Doe, and I made JohnDoe.com and proceeded to sell merchandise with YOUR name and YOUR quotes on it. I'm not paying you any royalties, and oh you want the domain name? Tough, you better cough up $250,000 for it.
Besides this being illegal, it's just a morally douchey thing to do.
If this was me, forget just asking for the domain name. I'd sue the shit out of them. But Ron Paul is a nicer guy than I.
