Facebook, the antisocial advertising platform on which anyone can promote just about anything, on Friday said it found people promoting political discord in the US and UK, yet again.

Russia doesn't appear to be involved this time. In the latest round of Whac-A-Troll, the data harvesting site said it removed 82 Facebook Pages, groups, and accounts for "coordinated inauthentic behavior" coming out of Iran.
