Troller is looking for a response...ANY response, and he will chum the waters with complaints, insults, compliments, and inflammatory tidbits hoping that someone...ANYONE, will take the bait. Generally quite harmless - practices a form of catch and release. Nonetheless, he can upset the delicate ecology of a discussion forum. Once a forum becomes aware of his presence, however, all feeding activity ceases and Troller must move on to more promising waters.
