The Pushdown Network
Organizations and Personal Email users are blocking/filtering millions of junk emails every day. This is to the advantage of spammers as it allows them to target the most vulnerable users who do not have filtering software or technical savvy. Beneath the protected networks is a wide-open "pushdown" network full of potential victims waiting to be scammed. It's called "pushdown" because we have created it by pushing down the junk by blocking, filtering, and deleting it. This is another reason why content blocking alone will not solve the problem. While you and I may be protected, those without protection are allowing their PCs to turn into zombie PCs and bringing infected files onto office networks. These people may end up being victims of fraud or identity theft and this effects all of us.
