After 12+ years of service they deleted my secondary email account because I hadn't visited it in less than a year ("username has been recycled"), then wouldn't let me re-claim the username, and have no support contact for it. I will never trust them with anything important.

You made me launch my old Yahoo account to be sure it's still there.

Then I tried to respond to an email in Yahoo! Mail, and EVERYTIME I HIT THE LETTER 'i' IT POPS UP A CHAT DIALOG BOX WTF. Sorry, but it's really frustrating.

I think they are responding to these kind of problems over Twitter now, though it might be because the user name has already be reused.
