I recently was emailed from HaveIBeenPwned.com (which I am signed up on) about the ShareThis website/tool (not signed up on).



I have no memory of signing up for that service.



When I go to recover the account (I might as well close/change password), I get this:



reset password page for ShareThis, but with an error message that reads: 'No user with that Address. Need to Register?'



The two facts seem incongruous:



Either I had an account and it was pwned, or I didn't have an account (and thus HIBP is in error)?



How do I find out the true situation, and what is the most secutre course of action?

From the FAQ:




Why do I see my email address as breached on a service I never signed up to?



When you search for an email address, you may see that address appear against breaches of sites you don't recall ever signing up to. There are many possible reasons for this including your data having been acquired by another service, the service rebranding itself as something else or someone else signing you up. For a more comprehensive overview, see Why am I in a data breach for a site I never signed up to?




It's likely some services allow signing up without confirming an email address, or that accounts that haven't confirmed email addresses are still stored indefinitely but cannot be logged in to, or any number of similar issues.
