Although I don't believe Jeb is a Troll. Considering this thread was his first posting on the forum, I can understand, based on the definition, why some may consider him a Troll.
Troll from netlingo.com:
In general, to "troll" means to allure, to fish, to entice, or to bait. Internet trolls are people who fish for other people's confidence and, once found, exploit it. Trolls vary in nature; here are four types of online trolls:
Playtime Trolls: an individual plays a simple, short game. Such trolls are relatively easy to spot because their attack or provocation is fairly blatant, and the persona is fairly two-dimensional.
Tactical Trolls: This is where the troller takes the game more seriously, creates a credible persona to gain confidence of others, and provokes strife in a subtle and invidious way.
Strategic Trolls: A very serious form of game, involving the production of an overall strategy that can take months or years to develop. It can also involve a number of people acting together in order to invade a list.
Domination Trolls: This is where the trollers' strategy extends to the creation and running of apparently bona-fide mailing lists.
Troll from urban dictionary:
