Looks like Chris Pirillo also got his Apple ID stolen. Like in my case, Apple has assured him that their processes no longer allow this to happen.
However, it seems that Apple’s procedures had not been improved during the two-and-a-half-week period between the two incidents. I’m not taking their word very seriously at this point. Also, the promise to get back to me about their log files detailing my account’s usage? 30 days on since their initial call, I’ve heard exactly zip from Apple.
