If artmarketblog.com is the site you are talking about, there seems a good reason of not being indexed by Google. I checked your blog and found that the domain is not only forwarding to a blog hosted @ WordPress.com, it's also cloaking (masked or stealth redirection) all the URLs.
I'm afraid a reinclusion request isn't going to help in this condition. Maybe John can guide you properly about this particular problem.
Edit: 1 I also checked in Yahoo! Explorer. Your blog doesn't have any incoming links.
Edit: 2 I just
checked in Google and found that artforprofits.wordpress.com is indexed.
