Oh no, but he was "making a point". Or he was young. He was "right" that it's bad to give up your info (so Zuck hammered home the point by scraping email contacts and using it to populate People You May Know. for your own good)

You didn't hear that out of Myspace or Friendster or anyone else that's trusted with information

Minimum threshold should be "People should be less forgiving of just giving away credentials but now that I have them I'll protect them with my life". Oh well. Apparently I'm just an idiot

He was just joking just like he was joking when he said he'd "fuck the Winklevosses in the ear"

Of course, we all make mistakes. Just like when he accidentally made a free VPN to spy on peoples traffic. Sorry bros, networking malfunction!
