I like the idea of it, but only in micropayment terms, not in "I will now make a secondary income by charging users 0.0001 BTC per email"

Some of these amounts are too much. Good way to get around spam though, maybe even fork out and create an "anonymous" messaging system that costs 21 sats.

Don't add a board to it aswell or else you get stacker.news 2 hahaha
