Did any of you have your alias as your username here or some sort of simple dictionary word? Wouldn't surprise me if hackers were using bots to try get hits on usernames and then focusing on the ones they find.
Doesn't it feel strange that all these strange things happens to one and only one online wallet, 99% of the cases is blockchain.info . Well after reading other stories here, I raise a reasonable doubt, why people should continue using it
If you can't keep your funds safe then using a desktop wallet wont be any good either. At least blockchain.info has several security features that prevent a hacker getting in. Even if they had your password and identifyer they wouldnt be able to get in without confirming via email and 2-factor if you have that set up which you should have and even then they wouldn't be able to spend the funds if you had a second password on.
