Just curious how do timestamp calendars avoid spam?
Discussion
They cost money
Yes but from the client side readme it seems like you can just get a timestamp from a calendar and it doesn't mention anything about payment requirements, like the on chain fee is covered by donations.
The current donation model would not work at full Nostr scale. They probably have some anti-spam measures in place already, but there would be a commercial model that replaces the donation model if this ever took off. IMO
