I have a question is it possible to change the email to your account? Or it can only be done by hackers? Or you will need to asked theymos to change the email?
Edit sorry for this question already know how soryry this is very nood of me.
If you are in the actual account settings you will be able to do it. If it has been hacked and you are no longer owning the account, only theymos can change it for you. :-/
Yep. Seems to be a trend here recently. I had the exact same thing happen to me (discovered yesterday). I seriously doubt my account was specifically hacked - seems more like a database hack or something (but I don't really know - I just know my password was strong).
Password strength doesn't meaning anything for an accounts, since hackers don't crack via password, but rather via .php or sql injections. They write a script to the database that makes it spit out the password to that account, regardless of what it may be. Even if it is very long you will still be able to crack it in the same amount of time as if it had been a much weaker password. (I think this is how it is done, however I may be wrong). The capctha authentication and 45 second time-out makes it nearly impossible to hack via password.
