A simple solution to spam calls/emails/etc. is to have a button that the recipient of a call/message can press which charges the originator $5 or so.

People pressing the "give me $5" button repeatedly for no good reason
-
You can do it once per call. If somebody does it to you for no reason, you don’t call them again unless it’s worth $5, which is sort of the point.
-
Can you have opt-in exceptions? If not, consider the scenario where someone bulk signs up for email marketing lists and bilks each one out of the fee once a first email is sent
-
Yeah, if you want anything like the current ability to request regular communications, you’d need something like that. Or maybe this is a reason it works better with phone than with email.
