AdsBlackList founded by Emir Pilavdzic, is a unique project which generates a list of blacklist URLs based on the site URL and set of keywords that you provide. You can then copy & paste these URL list into your Google AdSense competitive ad filter option to enable you to maximize your AdSense revenue with minimal effort —because, what you get is the list of most commonly filtered websites whose webmasters use AdWords to attract visitors for low price click so they can convert it to high price click on their own MFA (Made for AdSense) or Low Cost per Click site(s).
MFA: "Made for Adsense" a.k.a. MFA is specially made site for purpose of displaying google ads and gaining revenue by sending traffic using AdWords. If you're webmaster running Adsense on your own website, you've probably seen google ads with text like "We have found 4 best products for ...", or "Best resources on net for ...". Well in most cases, these advertisers pay you only between $0.01 to $0.03 per click, depending on your site PR (Page Rank), traffic and page views. So detecting them is very simple. If you visit them (Do Not Click On Your Own Ads) and see more ads than content, then you certanly got a winner.
LCPC stands for Low Cost Per Click, and it represents sites which clearly (but not 100% positivly) pay you very low amount per click. LCPC sites are usually trying to convert you to register for something, to buy something, etc.; while MFA sites are just trying to make highest CTR (Click through rate) as possible. MFA sites also pay you low per click so that's reason more to block them.
