This topic has been consistently ruled off-topic for NANOG by Merit's staff.
Please respect those of us who don't want to hear about spam here.

For those interested, the IRTF's ASRG is actively studying anti-spam
techniques and I'm sure they'd be interested in hearing all of your ideas
(after you verify they haven't been tried before).
