Why not use a Spam Filter?
First of all, spam filters do not protect your real email address from being harvested by spammers. Secondly, spam filters are by nature reactionary. It means that spammers always manage to be one-step ahead of the anti-spam vendors. Filters have to learn the tricks spammers are using and then learn how to stop them only to be attacked by a completely new barrage of tricks which they again have to learn. It is a vicious cycle. On the other hand, it takes spammers little effort to find ways around keyword filters or more advanced Bayesian filters. For more information on C/R systems drawbacks, go to the Compare page.
