Why do SOME people like to troll? They literally spend their days trolling doing that in 4chan, or, if the other site whether it's youtube, reddit or social they create a specific account in order to troll. Why they do this? Why so many people find this funny?
Is there some studies that show why people act this way? All I can think is "Bad attention is better than no attention" but it seems me like a too way simplistic way to see the phenomena
