All emails are deleted without any warning
I registered a backup email on Outlook. Every time I sign in on Yahoo there was always a notification email to Outlook. But now all of my emails are deleted. Yahoo does not send any kind of message or warning to my backup email at all.
All of my 15 years worth of mails along with accounts I signed up with Yahoo mail address is gone. I still can't believe Yahoo can just do this on anyone's data. This is why nobody use your service anymore.
