Here is what happened:
I made a wordpress blog about 2 months ago and it was indexed in about a week or so. After that I did some social bookmarking, got some backlinks (about 50) added a bunch of content etc. In few days, I was 15th for my main keyword which was awesome! Then I help adding a few backlinks here and there (some were spammy comment backlinks). But then, all of the sudden, my site disappeared from Google. Not moved to some XX page, it got deindexed. Site:http://mydomain.info (its a .info domain) returns a bunch of my pages, but index (main) page IS NOT THERE!!! My index page was a static page made in wordpress. At first I thought it was a google dance, but it has been about 5 days now and its still not indexed.
Was my website "sandboxed"?
Also, I noticed something weird in the webmasters tools:

Its still says that I'm ranking for my keyword!!!
btw, it's not a customized search from Google. I tried it on my cellphone, school's computer and my friend from another state!!
Could it be because I have some ClickBank adds on my new site? Could it be because I got "too" much traffic to a new site? (about 100-150/day) Also, I made a newbish mistake when I first made the site and interlinked my sites. (removed after few days). Other sites, however have not been affected.
Thanks for any help! I'm looking forward to your responses. My main question is:
What I Sandboxed?
