A lot of talks about MFA sites being bad. How many sites would disappear if there is no google adsense program? If there is none, my websites (50+) will surely disappear because I don't have the income and interest to make quality websites. Repeat - quality websites.
You just answered your own question...you don't make quality websites. Most MFA I've seen have little or no useful content with the only purpose being trying for adsense clicks.
Google relies on the people who use search - and those people don't want to land on a site that doesn't provide useful content. The people who click on MFA ads often do so as a way to leave the crappy site - which isn't good for the advertisers. Without visitors and advertisers, google is nothing. That is why they are weeding out these sites from their search results and adsense program. If you don't have the interest (because income doesn't apply) in making a quality site, then you should really be looking for something that you have interest in.
