Short-sellers aren’t known for restraint and decorum, and that goes double on Twitter, where Marc Cohodes vowed to take down a CEO he accuses of fraud. “I will bury the little fella in a shoe box,” Cohodes tweeted in October.

Weeks later, a black Ford Expedition pulled up to the short-seller’s Sonoma County ranch. Two FBI agents emerged. They showed Cohodes a printout of his tweet and a second one that mentioned loaded guns. “Stop sending threatening tweets” about the CEO, one of the agents warned, or else.
