No, because for 90% of those users the PSN password and the email password are going to be the same.
The only solution is new accounts and import trophies from the old one, but not anything sensitive.
I disagree Sony should send a verification to the default email address listed on each account. Peoples passwords might be the same but That is not Sony's fault. Any competent user should know to use a unique password for each service they subscribe too. Especially in cases where credit cards and other personal information are required.
I think its wrong that they didn't report the truth. That is what wikileaks is all about IMO.
They give you a 75kg sack and say "carry this shit down some stairs and out of the building." If you struggle instead of hurling the thing up on your shoulder and jogging out of the building, you fail.
Hate to say it by most people weigh more than 165lbs, especially in the USA.
But instead they just release these dumps, if only to say "500000 CABLES!"
I keep seeing people saying that they just "dumped" all these cables without going through them first. Even amazon has said "it is not credible that the extraordinary volume of 250,000 classified documents that Wikileaks is publishing could have been carefully redacted in such a way as to ensure that they weren't putting innocent people in jeopardy," I hardly believe this is true. You can check the wikileaks website yourself wikileaks.ch and see that they have only released 842 cables out of the 251,000 they have. Get that facts straight people. Do the research and use your brain.
