The lifeblood of spammer is email. They need to be able to send lots of it on an ongoing basis to stay in "business". High profile spammers can send 80 million pieces of junk email every single day. Yes one single person.
ISPs all over online world have vowed to stop spammers sending such vast amounts of email through their mail servers. Do they really keep their word? All end user sees is that spam keeps coming. There must be a loophole there somewhere. There is.
In soft white underbelly of internet there exists something known as a pink contract. The term pink contract comes from color of famous tinned meat that
junk email gets its name from. A pink contract is simply a business agreement between ISP and spammer. The spammer agrees to pay ISP to turn a blind eye to junk email passing through their mail servers.
Surely this is bad business for ISP? Well answer to that is both Yes and No. Yes it's bad news for people who receive junk email and No it's good news for ISPs bank balance. A monthly pink contract can pay ISP amounts from $10,000 upwards. Bearing in mind that average work-at-home spammer averages $100,000 net per year above figure is small change fo bigger junk email vendors (the guys who earn $200,000 - $400,000 per month.)
