Hi, I have recently worked on several penguine recovery project. I have found that those websites who are penalized have large scale link from different directories. Is that means that directories are not working for SEO or people should look for directories with high PR? Also it is a big problem to remove your back links from those. I have found a person who have 100 directories. When I have requested him he asked for 500$ for removal of those 100 links. That is absurd.
