I see trolls coming here all the time. There will be more over the next four days. They are signing up as we speak. They make one very short post, usually in the form of a question, then the split the scene. You ask them to clarify and they are GONE. I think a) check peoples sign up right away, and b) if something is odd, ask them to donate to FR as a new member.
LOL. I love those posts that say "Welcome to Free Republic" with a link to the contribution webpage.
