Thanks for the Ping.
Interesting posting history on that one. Taken in isolation, many of their posts appear at first glance to be of a quite conservative bent. In fuller contex and with the aid of Zot-assisted hindsight however, it’s obvious their goal was divide-and-conquer.
That is typical troll behavior. They stay cloaked and slowly start the little digs and hinky opinions every once in a while, until they come out and show their true colors and get the zot.
It’s an infiltration technique, but it doesn’t work effectively unless the troll can attain a position of power on the site. A mere observer and commenter really can’t do much damage, and he gets outed and banned eventually.
