Articles are submitted to feeders and article sites. Some have violated copyright laws by using articles made by other people and made it as their own. Many SEO's agree that article writing helps the site's ranking a lot and many have submitted several articles just to get their site noticed.

Unfortunately, black hat techniques are being used. Spam blogging, duplicate sites and other unfriendly techniques are being used to get their site to the top. I could not blame them because most of the SEO contestants have no actual experience in SEO before this contest and they are still learning the difference between ethical and unethical SEO.
