Well it really depends on what you define as forum trolling. If you are in reference to off topic posts with in a post it really depends on the case and the forum. I am normally all for it when it is deserved but I usually don't try to participate in it unless its in a forum and the mood is trying to be lighted. So the question is if I am for it or against it I am for it and against it. It really depends on the subject the trolling is happening in.
That's a fair answer.
Forum trolling is a state of enlightenment, you're able to see the irony or extreme levels of idiocy in a topic and you capitalize on it in unorthodox ways. Sometimes the user targeted has no idea he's being trolled, but that's not the goal.
The other people who read the topic may understand your subtle troll and they will usually agree with your position or delete your post. A secondary, but less important objective is outlined as the "intended response" in which you evoke a frustrated or angered response from the target to indulge your need for hilarity.
I ask you this question because there are two types of people in this world. The trolls and the been-trolled. It's really black and white, gray is for losers.
Thanks.
