Rob, this type of thing is just hideous. I HATE liars and cheats, and these guys are perfect examples of both. Legal action seems like it would be a big hassle with little pain on their end. What I suggest is simple. #1 keep up with contacting any site they post YOUR article on. #2 Create a small site documenting all the crap these towo guys are doing. Then make sure that whenever someone types their names (and related names) your little site shows at the top of the list in every search engine. Post a link to your little site here, then we can all start going to it and get the hint count up, plus we can pass it on to all our freinds. Heck, start a chain-mail type of thing. Hit 'em where it just might hurt.
