Why was my site banned

I'm desperate! My site was banned by G. I've spent a year on it. No paid links/spam etc. (social bookmarks only). The site is in my signature below.
It still has some PR but no pages in index. In webmaster tools it is still written:"Googlebot has successfully accessed your home page.
Pages from your site are included in Google's index."
Please advice how to get rid of it?

 

Just a thought... you're advertising pharmacy drugs. I don't think Google likes this, but you'd have to check out their Terms of Service to confirm it, I'm sure it says something about it somewhere.

 

ye, it is not that your website is not good, but what matters is that you are promoting some pharmacy drugs. it is possible a violation of google's rules.

 

I see but thousands of similar sites are in Google SERPS.

 

aha,
maybe your site is so good that google notice your site.
and then find the violation.
but you can communicate with google, they will tell you the reason.
and only they can tell you the real reason.
