Trolling (from Sameer's Post)

A true troll takes skill.
One would effortlessly post a remark to taunt any reader to waste hours composing an incensed reply with all caps and exclamations. That troll would continue with no deterrent and continue to lay down verbal traps that could possibly further irate the reader.
I myself do not have the skills to be a troll, but greatly respect them. It's reverse satire.

what I think of in a troll

Trolls for one have an upper hand in understanding the audience before he's even able to see them. He anticipates his target and profiles their annoyances to pick one that has most potential. Communicating the loaded message has to be persuasive in itself. He has to disguise his message using the right syntax, appearance, and conciseness to appear as the reader's most hated antagonist.

Once the message has been sent. The troll must continue undeterred, from any meaningful or discouraging replys. He must stay with his head strong, and continue feeding the fire. In part the more efficient he is, the more effective he is. If he is able to "troll" the message boards with 20 minutes of his time, while his victims are lured into a 2 hour trap, the more likely the troll is to relish in his accomplishment

In in part the troll is to appear as the message board's worst enemy: spreading hateful messages, while taking time and energy away from the community's ability to discuss their own topics. Thus they are often banned, but work around that limitation with creating false identifications and/or  with the use of proxies.

In short, trolling is the flip side of satire.
Satire is comedy of the many to laugh for a relevant cause.
Trolling is comedy of the individual to annoy for a irrelevant laugh.

Imagine Steven Colbert. For one side he's a satirist. For the other side he's a troll.
