[cap-talk] charging for spam. What are the implications

[John Carlson]

I think that the only way that charging for spam is going to work is:
1.  You have to give the recipient a one time revocable capability to  
charge the sender.  If it's not revocable, then companies can  
essentially steal money from each other.  If the capability is  
revoked by the sender, the message disappears if it hasn't been read.
spam cannot contain links which will notify the sender when the  
message has been received.
2.  Corporate accounts will need to be protected from disgruntled  
employees sending out spam the day they leave.
3.  If corporate accounts are protected, then corporations can spam  
and blame it on disgruntled employees.
4. Thus everyone will need to be personally responsible for the spam  
they send.  Not a bad idea!
5.  Corporations can choose to reimburse employees for the spam they  
send.
6.  Spam should be hashed, and duplicates discarded.

Again the spam is just used to establish an initial communication and  
contain information about identity (a certificate chain).   
Thereafter, capabilities are used to communicate.
