Penalized Web Directories by Google

I know how important web or blog directories are when we talk about internet marketing, it can provide a good quality backlinks. I was googling last night trying to find more blog directories and I end up with seomoz.org article what make a good web directory and why google penalized dozens of bad ones. I find out many web directories that has been penalized by google.

As a result all of these directories no longer rank for their trade mark names, Rand Fishkin (who condones link buying) does not like directories so he has been complaining to his buddy Matt Cutts and Matt has gone out and manually penalized a large number of the leading directories.

Good thing I didn't submit my URL to any one of penalized directories. We should be all aware of this things specially when your trying to build site's reputation.

Here are the complete list of the penalized directories:
