When we talk about "abuse" in real life, it usually comes in three forms: physical, sexual, and emotional. Since you can't physically nor sexually abuse someone over the internet, the abuse is perpetrated through the medium of a keyboard, with typed words. Ergo, trolling is a form of emotional/psychological abuse over the internet, and the intent is almost always to incite a "negative" emotional reaction in a person or group of people, which is usually nourishing and entertaining to the troll himself (and his audience) by way of humor and amusement.

I look back at what I used to do for fun on those lonely Friday and Saturday nights and realize how truly pathetic a life I was living. I had no social life, had never had a girlfriend or gotten laid, had substituted my mundane reality for a virtual reality, bought IP-altering software just for account bannings, and was just an all-around unhappy asshole who loved ruining otherwise happy peoples' days and bringing down their moods to the shitty one I was constantly experiencing. The reality is that, just as with real life emotional abusers, most trolls suffer from one or more various personality disorders (usually narcissism) and/or an inferiority complex, low self-esteem, and depression, as I was. Trolling is a cyber-expression of emotional abuse, and emotional abuse itself is part of a grander pathological mental disorder that the troll should seek help for, as I did.

Posting rude and distasteful comments, sometimes for the purpose of a reaction and other times not. Either way it is malicious and whether it is intended or not can have serious consequences. Those who troll will laugh at that, but trolling fosters an environment that leads to more serious abuse also known as cyberbullying where lines are crossed which should never, ever be--like encouraging someone who is suicidal to commit suicide. This is bad humor, and while in your virtual reality it may be funny, in actual reality it's not. It's time to grow up.
