I feel very ignorant - what is a troll? I'm new to this forum. Thanks.
A troll is someone who baits internet discussion forums with controversial topics and posts guaranteed to get a rise from other posters. The name "troll" comes from the fishing method known as "trolling". On the internet, trolling is introducing some tasty flamebait into a thread or a board in order to generate more heat than light. A troll is not interested in even-handed, polite discussion; they are just attention seekers.
