There's a nice-looking directory which used to have something like PR 5-6. I was about to send a site for listing there, and today I found the site is gone from Google SERPs! Also their PR is gone as well. I don't know what happened to it really. It does not have huge listing, but at list the idea was original, or well, I've not seen nothing similar but the verbs in gimpsy. This let very clear, that Google is in a clear war against directories.

I cannot imagine a directory that sees it's sustenance in search engine traffic - especially, sustenance that's essential to its success - as being any more than a temporary scheme to make a few bucks "whilst the sun shines" or the SEs remain open to the latest SEO ploy.
Now, don't get me wrong. There's been plenty of people who have used this approach to make hay. However, for anyone creating a directory with more than that in mind the "essential interdependency" model is bad architecture IMHO. Yes, such traffic is great, but it better well be only 1 of a dozen sources of merchantable traffic if you're in the business of directories.
Weanings aren't wars. They're tests of fitness for survival.
While I agree that a directory should not rely on search engine traffic (just like any other legitimate web business) I think being de-listed like so many have on July 28th is over the top.
A grey-barred directory is different than simply not receiving any traffic from Google. It's more like Google saying that your directory is evil, which would make it difficult for a directory to get people who wanted to be listed, as well as advertisers.
