The email provider that account was tied to doesn't exist anymore, and the domain is taken. I didn't notice until after it happened, so I am not putting all the blame on reddit. It's more of a string of unlucky circumstances. Who knows if I could have even changed it without access to the email account, anyway.

Fun fact: Reddit for the longest time didn't require an email address to create accounts.

Reddit still doesn't require an email to create accounts, even if it now heavily implies it does. Just click next without entering one.
