I have no idea what this is about, but I'm going to guess that someone created an account using my email address.
However, I don't want to get any emails from you.
I just got one, and there was no unsubscribe option. My first reaction to any unsolicited email that lacks an unsubscribe option, or one that requires me to sign in or recover a password, is to report it as spam.
I have looked at the account options and I do not see a delete option or any way to request zero correspondence from this site.
That's what I want: zero correspondence.
