Decided to visit the website to delete my account. Lo and behold, the "Deactivate Account" button kicks off a perpetual loop that asks you to "Sign In Again To Delete Account" then dumps you on the same profile setting page, which prompts you again to log in... so you can't really delete your account, at least on web, without the help of support.

Edit: figured it out, is confusing

1. Remove social connection if this is how you logged in 2. Log Out 3. Upon login, request a password reset 4. Reset and login 5. Request Deletion 6. Enter newly created password
