Deleted account
Surprised to find I had used Google to authenticate with them at some point. Wouldn't let me delete the account until setting a password though. So I did, "deleteme", then deleted the account. All a bit late, but these breaches are far too many and frequent now that we may as well give up all hope of having anything not widely known about us any more. Like most incidents like this, I just black-list the service and never use it again.
