If you do that, you can also make pinned notes that can be used as ads.
As long as the sender maintains the biggest zap to devs, the note will remain pinned to top of the feed. Can be checked every hour or every 24h, depending on the demand. 

 we should be able to get that with NIP-66 and the stuff  @sandwich built:

nak req -k 30166 -t N=50 relay.nostr.watch -a 9bbbb845e5b6c831c29789900769843ab43bb5047abe697870cb50b6fc9bf923 should get it, but I see it's returning non-NIP-50 relays 🤔

kind:30166 with "#N": ["50"] should get that info 😀 

 Hmm, I just ran a test and more or less got what I expected. Here's the test result:

Can you provide replication instructions? 

 You're missing `since` btw. 

 Also don't you need to encapsulate `50` with double quotes in nak? `"50"` :D 

 has existed for almost two years.
