@Liberapay meant to address this thread to you, see above
(Other than exploiting your login form as an oracle, which is currently possible but I'm not going to do for real obvs) #security
Hey @liberapay I've redirected some of my patreons over to you. Problem is, only half of them seem to have actually started using you, and I don't know which half.
I realize that you obscure donor information for a reason, but it would be very helpful to have a limited way to check if an email address is currently even signed up at liberapay at all, especially in this migration situation.
