I'm surprised there aren't more defamation lawsuits on the internet. I've thought it could be a moneymaker for social media firms to automate defamation shakedowns, just like copyright trolls automate copyright shakedowns. Help those defamed find and the messages and send out "Pay $N thousand and this defamation lawsuit goes away now" messages. Back up some of the lawsuits with $$$ to show the threat is real.
