AdsBlackList.com is a unique project designed to enable you to dramatically reduce the amount of MFA (made for ads) and LCPC (low cost per click) sites which appear through the use of PPC systems such as Google Adsense™, Yahoo Publisher Network™ and Chitika eMiniMalls™.

To get started with this service, you’ll first have to create an account for free. You can submit your sites and the popular keywords for your site. This service uses these keywords you define for your site to generate a list of MFA and LCPC sites. You can take this list of sites and add them to the Competitive site filters in your Google Adsense account (Adsense Setup>Competitive Ad Filter). This means that ads from the filtered sites won’t come up on your site, and effectively increasing your earnings.

The free account from AdsBlackList is limited to just 200 sites, which is fine for me, since Adsense allows only 200 URLs in the Competitive Ad Filter.
