Look around on the internet for definitions and you'll soon find out that's not a widely accepted definition.

From Wiki:

In Internet slang, a troll is a person who starts flame wars or intentionally upsets people on the Internet. This is typically done by posting inflammatory and digressive,[1] extraneous, or off-topic messages in an online community (such as a newsgroup, forum, chat room, or blog), with the intent of provoking readers into displaying emotional responses[2] and normalizing tangential discussion.[3] This is typically for the troll's amusement, or to achieve a specific result such as disrupting a rival's online activities or manipulating a political process.
