A 16-year-old Canadian male has been arrested for calling in over 30 "swattings," bomb threats and other hoax calls to emergency services in North America. The young man is alleged to be the operator of @ProbablyOnion on Twitter, which had previously advertised swattings (sending SWAT teams to your enemies' homes by reporting phony hostage-takings there, advising police that someone matching your victim's description is on the scene, armed and out of control) as a service, and had bragged of swatting computer crime journalism Brian Krebs twice. Krebs had previously caught a kid who swatted him, and outed him to his father — this may have made him a target for other swatters.

Minutes after my local police department received that fake notification, @ProbablyOnion was bragging on Twitter about swatting me, including me on his public messages: "You have 5 hostages? And you will kill 1 hostage every 6 times and the police have 25 minutes to get you $100k in clear plastic." Another message read: "Good morning! Just dispatched a swat team to your house, they didn't even call you this time, hahaha."

I told this user privately that targeting an investigative reporter maybe wasn't the brightest idea, and that he was likely to wind up in jail soon. But @ProbablyOnion was on a roll: That same day, he hung out his for-hire sign on Twitter, with the following message: "want someone swatted? Tweet me their name, address and I'll make it happen."
