In a perfect relay, I would like:

-to always be able to connect

-to filter spam (airdrop bots etc) without anything else other than criminal activity

-to always broadcast my notes to as many other relays (blaster)

-to be able to easily rebroadcast my notes and backup

-to notify me if my notes are going to be deleted, so that I could back them up myself

-to remind me to pay up for the service in a dm (subscription, or splits, does't really matter.)
