Can we use DMARC to ask Gmail to close registrations? Google Calendar to allow far fewer people the ability to send invite notifications? Firebase to close registrations? Azure? Microsoft 365? AWS SES?
replyIt feels like the biggest spammers have swung back to just abusing SaaS and getting SPF / DKIM / DMARC for free from one of the big email providers.
Exactly this. Spammers have the technical competence to overcome any technical hurdle, so using evidence of technical competence achieves nothing.
replyIf it were possible to charge $0.25/email for delivery, I'd be more than happy . However, I'm sure large tech firms will need to say that is "too hard to implement at scale".
Stamp costs don't stop snail mail spam, either, unfortunately. I would be concerned if we added something like bitcoin fees to email delivery rather than curtail spam it would just further encourage grifters seeking ROI on their spam deliveries.
replyWhat if a single email cost $0.001 cent to send, and it was paid to the recipient? For $10, you could send 10,000 emails. For recipients, every 1,000 emails they get is a dollar in their wallet. You’d need something like a blockchain for this to work because the traditional payment processors still haven’t figured out micropayments.
replyWhat spammers are using the same domain for longer than couple of hours?
replyWhat do you expect to achieve by blocking an already abandoned domain?
They're generally hosted on a google or microsoft 365 or something slightly less shady. Good luck with that.
