I've actually paid for it a while back before realizing that I added myself to a honeypot. I'm not lying when I say I'd be a user without the privacy issues.
Maybe it was an email code or something like that I don't remember.

Yes we use OTP to login / signup instead of passwords - which are security holes.
We’re not against adding Nostr as a login method, it just doesn’t seem to be this massive privacy improvement from what we’re currently doing.
