I can see adsense preventing publishers to filter low paying ads or MFA sites ads soon ... I have put more than 50 MFA sites in my filter list , still though i am getting 0.02/ click instead of 0.01/click .. My niche is a low paying one .. Does anything see this also ? I really think Adsense will prevent us from filtering low paying ads in the near future.
Filtering low paying ads is not going to help you any if the only ads showing up for your site are low-paying in the first place. Google has no reason to stop you from blocking ads - but you are probably not helping yourself by blocking them. It means there is less competition for your already cheap space.
I tried to block some MFA-s for some time but as time goes new one's come out quicker than me blocking them so I removed them all from the block list win or loose? I do not have the daily time to find out
In my opinion, filtering doesn't do anything. In fact, after I removed the filtered ads, I noticed that my earnings increased by almost 50%.
