I changed my password around 8:30PM USA west coast time June 16, so it was after that they got the data.
http://blog.zorinaq.com/?e=55 says "...Contrary to previous claims from the MtGox owner, this indicates that many accounts had been compromised for at least days, if not weeks, before today's attack. This may explain some of the reports of Bitcoins being stolen from MtGox accounts in the previous days and weeks, as reported on the forums."
Something doesn't add up. My password on the posted .csv was created on the evening of June 16 west coast time. If blog.zorinaq.com is correct, then there were at least two separate seizures or losses of user lists from Gox, the first being long before Friday's release.
What am I missing? I am not the smartest rock in the forest.
