Social media is a terrifying beast. Like all beasts, Twitter, Facebook and the rest can be tamed, caged and made to do a few tricks. But when it decides to jump out of the cage and have a go at someone, then god (of instant injustice) help the poor victim! Only someone who has been trolled mercilessly would understand what the social media could really do to reputations. Had Mahatma Gandhi been alive now, he would have perhaps learned that the real practice of ahimsa was in not blocking a troll.
