"Freepers": pejorative for members of "Free Republic" forum; and by extension any who hold those "values". We also have lurkers and troll behavior that pops up at DU from time to time when they attempt to infiltrate. Quite a lot of fun when one drops his mask and is pounced upon en masse. (Although it's against DU rules, new members with low post counts are often suspected of freeper under the radar.)
