I have one more piece to add to the thing about what trolls are. On some websites (including one I'm on) they will try to eek out information they
have no right too. The best example I can think of is
F-16.net. There are a LOOOOT of people with clearance and a lot of
the discussion focuses around classified information without actually revealing it. There, trolls try to goad people into revealing classified
information that hold. We've had several members get busted by the men in black suits. I'm actually a little surprised by the fact that ATS
doesn't have a warning not to post classified information, but that might be from being on f-16.net too much.
