You can make multiple Twitter accounts with an email address by simply adding +word on your email address. So like, I have a few accounts, one is email@example.com, firstname.lastname@example.org etc and all the mail comes to the same address.
However, I chose on every account not to get email notify, and foolishly deleted and reinstalled the app - losing all logged in data. I regained all the accounts because I knew the handle, but I can't remember the handle to one of them - and it's a private account so I can't see if I follow it or if it follows me.
Phone number isn't connected.
Is there a way to see all the accounts that I own with that one e-mail address or any other way to reach that account?
