MySpace's latest effort to improve security against hackers and phishers has resulted in many, many users being locked out of their MySpace accounts, with no way to retrieve or change their password and get back in. Several people who have experienced this problem have posted comments to our post about the MySpace password retrieval page.
The blogger who runs the GhettoWebmaster.com site (not a big fan of MySpace when it comes to the technical quality of their product) gives an illustrated depiction of what's happening in the post "MySpace inadvertently flagging accounts as phished". Take a look at this if you've gotten the "Your account has been phished" message.
Fortunately, it appears that MySpace finally corrected this problem -- or, at least the captcha image problem is fixed. If you were previously locked out, try resetting your password again. Now, you should be able to see the captcha and correctly enter it, to give yourself a new password.
