i hate these sites best8sites.org 8bestsites.org best4sites best10 sites they all mfa they have huge group of sites with similar names when tried to filter them i discovered more sites with new names seems like part of same group. do you guys noticed these sites ? how we can to get rid of them ?
you really can't get rid of them...and although they may be doing well now, in the long run, I believe that quality content and backlinks to other sites would drop them out of the top serps.
You filter MFA sites because they normally offer low money per click, legit sites on the other hand pay more.
The legitamacy of a site is also relative. All types of sites are needed. To know how good a site you have, you need such crappy sites too! This in itself provides an intuitive way of rating each website. If it is only a question of low ad rates, you can always filter them as checksum said instead of banning the sites themselves. (I hope this does not give an impression that I am an advocate of MFA sites )
they have huge group once i filtered 5 of them i found new domains i think they only getting traffic through adwords ,sites like this can not have an audiance.
