I'm also concerned about an atmosphere of paranoia developing. I worry that posters will be afraid to disagree with OPs or address each other bluntly for fear of being suspected as a member of the "secret troll group." Quite honestly, if the responses to Siotehcat in the "teenagers doing chores" thread are an example of this group's "cyberbullying," I think that word does not mean what you think it means. (Not to pick on Siotehcat, and I do agree with a mod's warning posters in that thread to drop it, but I think there is a huge difference between questioning a poster's admittedly unusual stance on an issue and harrassing that poster.) I was bullied myself as a child and don't like to see bullying trivialized by applying that word to mere disagreement and bluntness. The other example mentioned in this thread, of ehellions sending friend requests, also strikes me as innocuous. I'm hardly a prominent or popular poster, but even I am FB friends with other ehellions.
My point is, I would hate to see disagreement and plain speaking become a sign of "trollhood." I appreciate it when other posters question and expose actual trolls who are playing on our emotions with made up stories. I believe that if someone posts in INAH every week about the same problem but refuses to accept any suggestions on how to fix it, we should be able to suggest that they are contributing to their own problem.
