It is quite easy to get your average site penalized, meaning they are not a mega company.
Business or E commerce sites that would never get natural link are easy targets now.
Load up your target with over 1k or more blog posts, watch it rise in the rankings for a month or two. Google sends out there GWT message, wait another couple weeks to a month then the site tanks.
About a two to three month overall process, and would cost a max of $200. If you think this bogus your in denial or have not done your homework.
