I had my account hijacked over the weekend. Been fighting with Yahoo Security for 3 days trying to prove I am the owner. Like others, I have had this account for a very long time, and the missing information is the 'secret answer' and I sure don't remember using "Who's Hungry" as my prompt!
I tried sending a PDF of my driver's license to Yahoo Security, and received an answer this morning that only supplying *all* of the registration information would allow me access to the account.
You would think that given the forum here, and Yahoo's knowledge of it, that something would be done to alleviate all of the hoops that you are forced to jump through.
I still have no access to my account, and it doesn't look like Yahoo is giving me any options other than to guess the 'secret word' that the hacker set up.

This is absolutely terrible. If I ever get access back with Yahoo, I am dropping them as soon as possible.
