The - tag should prevent trivial republishing; the rest is just good old pirating which will always exist.
Personally i think the zapbox relay model would work best:
follow = get free feed;
Pay = instantly just get the free+paid content aswell in the feed.
Most frictionless, client independent experience for the user. Publishers need to make sure they use the right relays that will comply with their chosen witholding scheme/metrics.
I lean toward the zabox approach too. A client could display those notes in a subscriber’s main feed, marked with a special tag or badge indicating that they’re seeing those notes because they’ve supported that author/creator. That communicates it as a reward and also encourages them to keep zapping that author if they want to continue seeing those notes, without feeling like the author is begging.
Zapbox itself might be a little bit bare; but a simple NIP for some receipt such that regardless of payment method, publishers could make it clear to the relays used what npubs are supposed to receive what should cover most usecases (including tiers and whatever).
The 'badge' is a nice idea, could indeed be a simple tag inside the event.
Boom, we just fixed substack, podcast subscriptions and whatever else.
Now im busy figuring out the spec for kidstr/TEPP (trust extended permission protocol), so someone else picks this up including a decent podcast standard and we can kiss RSS goodbye.
