I am not sure why people do this but they do!
From my own experiences, I can only see that it relates to the anomity of the Tinternet and nothing more because most of these 'Trolls' wouldn't be brave enough to challange people face-to-face.
It's reminds me of the time when I was in a town centre in West Sussex out for a few bevies with the boys when someone decided they were going to cause agrow.. they kept shouting 'Come on then' but as they were saying it they were stepping away from me... my point: all talk and no bollocks!
