troller

One who fishes by trolling.

An engine-powered fishing boat, used for moving slowly while fishing lines drag behind, sometimes able to sail in shallow water.

A troll; a user who maliciously provokes others.

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.
