Internet trolling made Justin Bieber's popularity, profit, success in life sky rocket from the attention.
This random google image graph thingy I found is a good example, clearly made by a basement dweller, but in fact by making this graph to troll, he is making the reality of the graph upside down, just flatten the peak out to where the peak begins.
Another great example is right here in this topic, he gets a cut of profit for views of that episode of CSI, haters hate JB and "like" watching this video, they show it to others, they get people interested in the episode to watch him "die", people watch that episode, he makes money.
So people who hate Justin Bieber for no reason at all, keep it up you're definitely hurting him.
