I run several directories that do pretty well in Google, but as of this morning I see that one of them has been de-indexed by them.

The site is about 2 years old and is squeakey clean as far as SEO goes, but today it is gone from Googles SERPs and is now PR0.

I'm not concerned for the loss in traffic, because it pretty much gets its own traffic from regular users, but I would like to know if I did something wrong. I sure hope that it doesn't happen to any of my other directory sites, but without knowing why one site was de-indexed, I don't think it would be wise to make any changes.

Are there any other directory site owners who have had their directories de-indexed lately?
