As for me, it appears that in the World page (
http://www.bluefind.com/dir/54.php) the reason of the gray PR bar is because of 3 links on it...
- www.chicago-condos.net
- www.worldinfocountries.com
- www.dirone.com/search.php?about=world
This 3 websites show a gray PR bar, so I guess BlueFind is getting those pages devalued with a gray bar too because of linking to "bad neighbors".
