The definition of an Internet Troll on Wikipedia is:
a person who sows discord on the Internet by starting arguments or upsetting people, by posting inflammatory, extraneous or off-topic, messages in an online community (such as a newsgroup, forum, chat room or blog) with the deliberate intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion, often for their own amusement.
To put it more simply, Trolls are shit-disturbers! Parden my language but that’s what they are. They are annoying, potty-mouthed bullies that are there for no other reason than to cause shit.
You’ve likely seen them and didn’t even know it. I know I have. I’ve been to some blog support sites where people ask legitimate questions and people comment. Comments come in and they start out helpful but then quickly digress into content that has nothing to do with the subject and language deteriorates into profanity and name calling.
I have seen the same thing in the comments section on YouTube and it’s big on the gaming sites – probably because these are most often frequented by teenagers.
I’m not sure what kind of person garners enjoyment from Trolling but they really need to find a better use of their time. And maybe they need to find some friends.
The best way to deal with a Troll is to simply not engage them. Don’t be dragged into the drama they’re trying to create. As soon as you see that the conversation is turning ugly and you suspect a Troll, get out!
I know it’s not fair that you are the one that has to leave but, as my grade 4 teacher used to say,
it only takes one bad apple to ruin it for the whole class
