I was talking to someone about ways Nostr could develop to deal with spam, long-term. We talked about doing something along the lines of SN's increasing cost of posting, but then I had an idea that I wanted to run past everyone here.
Spam exists because marginal costs are very low and slightly below marginal benefits, so mass messaging can become significantly profitable. It wouldn't take much of an increase to the marginal cost to radically reduce spam.
What if each user could set their own price for commenting on their notes?
This takes care of spam and has some other benefits to the user experience. We all have different preferences for engagement and this would give users an enormous amount of control over the value they're getting; both in terms of user experience and remuneration.
Thoughts? What other ideas do people have for managing spam?
