There is a particlar someone who has published sort of a homemade MFA site with about 50 pages, each on a different topic and each with a few lines of useless text then lots of AdSense ads.
It seems this person(s) is just copying the same site and publishing it again and again under different domain names. The new domains keep popping up on my site in AdSense ads and I keep blocking them.
Is it possible that enough publishers are blocking such sites and the MFA's are having to constantly switch domains?
Or is that too optimistic and instead, are the MFA's so profitable they are just repeating the same thing under a number of domains? Since they are advertising their MFA sites using AdWords, I don't think they have any concern about a duplicate content penalty.
MFA sites just take revenue from real content publishers and worse they are a waste to the advertiser so they end up NOT advertising or reducing their advertising which reduces the ability for the rest of us to make a living. They are just scum and I hope Google gets rid of them all.
