I wish there was no unlimited calling and texting. 1 cent per minute/text is ideal. cheap enough for everyone to afford and expensive enough to make massive scale spam calling business unprofitable. same for emails. make emails cost 1 cent per email that gets donated to whatever good cause and watch spam drop by 90%

i feel like it would be effective but i worry about requiring payment information for sending emails. it seems like a privacy nightmare

Also, this gives a way to entities who control the payments control who can send emails.

Might be a concern in authoritarian regimes.

Weren't there a project with proof of work?

blockchain-based emails would definitely be a zesty solution
