Link spammer

I've just learn something, spammer is a job and it seems to pay well:

Sam (...) lives in a three-bedroom semi-detached house in London, drives a vintage Jaguar and runs his own company. But "it's not not all rock and roll and big money", says Sam. What isn't? Spamming websites and blogs with text to pump up the search engine rankings of sites pushing PPC (pills, porn and casinos), that's what.

I thought they lived in russia or brazil...
