Ask HN: Does this service exist? Lookup and bulk delete all my online accounts?

Dear HN,

Over the years, I have registered for many different services, email subscriptions, and the like online. I worry about how much of myself is out there that I have simply lost track of or forgotten about.

Is there a service where you can look up all these accounts in one place by email address, and manage/delete them? I'm talking something beyond the bulk-unsubscribe email services like Unroll Me. I want more closure than that -- full account deletion. Is there such a thing?

Thanks!

BTW if this doesn't exist, consider this some startup idea validation! You have at least one sincere customer willing to pay for such a thing if it exists. I suspect I'm not the only one.
