Through google's webmaster tools you can issue a re-inclusion request - there is no guarantee they will accept it though - or when they will. They say that right up front.
Quickest way to see if you domain is included or not in any search index is to simply search for it by url - mydomain.com. If it's not there, it might be that they have just never indexed it - so don't think it was banned when it might not be!
There is someone offering these autoblog - scraped content websites right now on NP. I feel sorry for those that might fall into this trap, but then who can blame the search engines for looking out for their own users by dropping these websites? They offer nothing original and right there according to googles terms of service it says you are not to use such a method with adsense. And in their webmaster guidelines it says clearly, and I quote, "Scraped content: Some webmasters make use of content taken from other, more reputable sites on the assumption that increasing the volume of web pages with random, irrelevant content is a good long-term strategy. Purely scraped content, even from high-quality sources, may not provide any added value to your users without additional useful services or content provided by your site."
And to make sure you are paying attention to the above, "Google will take action against domains that try to rank more highly by just showing scraped or other auto-generated pages that don't add any value to users."
I'd post that in the sales thread but, people should ask questions, and most certainly read what is easily found! And it's probably against the forum terms of service
