Lets be honest trolling is fun when it is done right! lets start whit that.
Some might think it's cyber bullying, but lets be honest there is a big difference between the two.
For example trolling is the art of getting people to react, basically having them waste their time on something useless.
While cyber bullying is more something practiced by edgy teens mostly focusing on one person mostly just as a way too feel good about them selves this sometimes takes the form of shaming for how they look, And lets face it we have all seen the teen drama's and propaganda clips.
But trolling real trolling is more like a game then it is about abusing someone, granted sometimes it might be mistaken for abuse or threatening but it depends on the target, if you take for example sjw's feminist's and other activists you will find that they are too easily offended by basically nothing.
But sometimes you just have too know what too type and when to type it, sometimes not much is needed like for example a drawing of a certain frog is enough to trigger a would be president that didn't even know what she was talking about.
But now for the morale of this story.
That 12 year old squeker calling you gay for nothing over the microphone isn't a troll. that just a little kid who's parents should have known better.
No real trolls are artist's and experts in psychological warfare.
