So: here you are, three British girls endowed with free time, low intelligence, no morals, a video camera… and a kitten. So how do you spend the time? Throwing the kitten, naturally. Knocking it unconscious by flinging it around and bouncing it off walls & ceilings (spoiler alert: the kitten is fine, and got adopted by another family). Then of course, posting the video tape of that super-fun session to Facebook.
So: here you are, Anonymous, and you find this video. What do you do? Why… use your trolling superpowers to find out who the girls are, what their names, addresses and relatives and school administrators names & contact info are, and then spreading this info across the cat-luvin-Internet. (Spoiler alert: the two girls on camera were nabbed by the British police, were put on trial and were dealt with as harshly as the British legal system can: a small fine and a stern talking-to.)
As lame as the legal remedy against the girls was, having come to the attention of Ye Olde Internet is going to be a mistake that will pay off against them for years to come.
