did someone just re-invented hot water again?

I don't think paywalls aligns with the value4value model SN adopts. I assume the idea here is to provide value for... whatever are you going to get back will be driven by the value your content provide to the community.

No sats? No problem, probably your content was not aligned with SN values and would better suited to other platforms/communities.

Suggestion: learn how to use the search before posting, it will save you a lot of precious time ;)

PS: second suggestion keep SN clean. Thanks
