Man these days AI is able to generate npubs and eCashu tokens so easily that will spam your inbox anyway.

Spammers will pay me free sats, really? If they keep spamming... then the "minimum sats threshold" isn't enough and it's going up!

Spammers will be happy to overload your inbox for such small amounts, whatever the amount get returned or not.

I mean spammers will still spam Stacker News too... however they keep paying and not get any sats 'free'... so it's a huge improvement.

The receiver should actually keep it as I assume it will need to signup somewhere to use the service.

No, no sign-up just an npub.

Anyway, email is becoming so obsolete. The only thing keeping me using it is GPG

I want to create for email what the guys have created for reddit/Stacker News and I am going to do it.
