sorry you can disregard this one. Just found out we had a tremendous boost in backlinks two days ago, that probably got us penalized or worse...banned.
I think it's blacklisted for spam http://www.whois.sc/pointcom.com Look at the line under the US Flag.
You get blacklisted for this too. "The owners of the main domain just added several hundred if not thousand domains to their raid server many of which point to this domain."
If you can't list sites legitimately with it’s own content then why have them? Search engines are blacklisting and removing people for this type of behavior and making dummy pages to point to sites.
Or possibly the SEO for the main domain. I've read that subdomains generally don't affect the parent domain. Then again, I've also heard that sometimes PR will just magically do this for a few days. If it doesn't bounce back up, the site's probably a wash.
