Somebody appears to have hacked the Twitter account of Dr Jack Kruse who was to speak on the Low-Carb Carnival cruise ship. A tweet was sent out suggesting that he was planning some kind of bio-terrorist attack. The FBI searched his room and arrested him. Although he was eventually cleared, the ship’s captain refused to let him re-board. It’s unbelievable that some anti-low-carb nut-case would stoop to this kind of thing. Let’s hope the perpetrator is caught and punished.

Update: it appears that the Twitter account used was not Dr Kruse’s personal account but one called “shitkrusesays” whose major contributor is known and lives in New York according to this more recent report:
