My business directory banned

I just wondering why my business directory was banned by google, the site is pr 4 with more than 39K pages index and when I check this afternoon I find out all pages gone and pr gone too.

I don't understand why? Does high keyword density cause this problem?

Is there a chance that my site banned will removed?

 

What's the url?

 

Sory pal, but I choice not to mention the url of the site in public forum for personal reason, hope you understand.

I just want to hear others experience who have been banned before what they do to getout from banned.

Does changing the site content or the whois of the domain helps?

 

business directory.. is it associated with dmoz?

 

edpudol:
if you use black hat seo techniques...
Keyword stuffing, Invisible text, Doorway Pages and more...

 

You have to first figure out what got you banned and change it. Without the url no one here can advise you on that.

What prompted you to write what you did above (since you don't want to post the url)

 

There are more than 100 directories banned by google. You can be one of them

 

Let me take a guess........ let's see

Oh shit there it is. 39k pages. Google must of thought it was spam........ either that they didn't like your writing style.

 

I got a directory removed too, 80k pages. dmoz clone.
