I will have to stick my neck out and disagree. Paid relays aren't the solution. We need to keep working on this. We need proof of work relays. We need an option to pay with sats to post (like on your phone, to avoid battery drain). 'Paid' relays don't fix spam, it just creates a little garden with high fences, for you and a few friends. 'Paid' relays should be optional. They should provide optional features like skipping the sats to post or work, or priority on bandwidth, NIPS05, backups, etc. If we paywall this shit, it'll never defeat the mainstream systems of control, leaving millions behind. We must do better than pretty gardens with high fences. We want everyone to be free.
