In Internet slang, a troll is someone who posts controversial, inflammatory, irrelevant or off-topic messages in an online community, such as an online discussion forum or chat room, with the primary intent of provoking other users into an emotional response or to generally disrupt normal on-topic discussion.
I’ll be the first to admit that without the trolls, there would far fewer than the 8,391 comments we have on this web site. Nevertheless, if you want to discourage trollishness, the best approach is a a minimal, and non-emotional response. An Internet troll is like someone who pokes an ant hill to watch the ants race out.
So, let’s be human beings, and not ants.
Now if I can just follow my own advice 😉
