Microsoft Preps Pay-For Spam Scheme
Gates also said in the same interview that Microsoft is considering another research-developed technology that would delay by a number of seconds the delivery of spam to users inboxes.
The pay-per-spam scheme is definitely the more radical approach. Microsoft Research (MSR) has been dabbling for years with the concept of making spammers pay: in cash, in compute cycles and/or in memory cycles.
Microsoft Researchs idea for this is called "Penny Black."
Spam costs users time and network providers money. Microsoft wants to shift the cost burden back onto the spammers.
