I don't know about all that because twice now I have been able to get Yahoo to get my account back after it was hijacked. This last time, I got phished and was trying to get back my account for 3 months. And its a free account so I wasn't hopeful to get it back but after some communicating back and forth and some detailed info about my account and such, (my alternate email no longer functioned because they disappeared from the net) they sent me another password to the email of my choice. If you signed into any photos link and it didn't show you anything or it brought you to your account, then you were phished by a hacker. Find out what happened and go from there.
