Paid relays are the answer in my opinion. Otherwise, itās just playing their game of whack-a-moleā¦ Nostream supports payments so now I have fewer incentives to implement other forms of spam prevention.
That said, anyone should feel free to submit a PR to Nostream or a feature request with a bounty to incentivize its development.
Have you thought of a way to create a market for relays? Imagine a user specifies they are willing to pay 1000 sats annually for relay access. Their app automatically connects to the marketplace, gets a list of relays, checks their prices and specifications, and subscribes to a set of relays. This approach has many pitfalls, but it could offer a better user experience than having users manually select and pay for each relay.
