PayPal is certainly trickier. I felt more comfortable testing with buying Amazon Prime through an Amazon account, because it would be easy for them to refund.
I assume I thought of trying to remove the email address! :) I sometimes forget they’re not necessarily the only identifiers, and some accounts let you use a mobile number instead. Probably there wasn’t a mobile on the profile.
It would be nice if all accounts used a username, and allowed you to not have an email or phone if you tick a box saying “I don’t care if I get locked out of this account forever if I forget the password”.
