It sounds easy, but unfortunately many email users do not follow this one simple rule. If you do not allow the spammer or spammed site to gain any hits or purchases... the motivation to keep spamming will diminish.
For example, if I advertise on Google for one month. Within that month, my ads gets 6 million views but NO clicks, NO purchases... nothing. With those type of stats, I would have no other choice but to stop that type of advertising because it simply does not work. Lets make this happen with spam. If everyone just quit buying the stocks, purchasing cialis/hoodia/viagra or trying to talk to person waiting in the cyber cafe... email just may get a lot less annoying.
For my home spam solution, I have found that Cloudmark (aff link) suits my needs quite well. They have a free 15 day trial.
