This is why people who say "ignore the trolls" are idiots. The internet makes trolling permanent and a mob affair. Your best strategy now is to fight back with your own better words, pranks, and trolling or else everyone simply assumes your silence means the mob is right.
Trust me on this, I am probably one of a handful of people who has been on the receiving end of a massive hateful mob and managed to kick the living shit out of them with just a blog and some hilarious jokes.
