can you just give the url of your site so that i could see if its really banned or just a penalty because both are different issues... probably you should submit your sitemap to google to help them know and hope that they could initiate the crawl...
www.want2fun.com is url and i think it is now banned or sandboxed by google. I have many times submitted sitemap but it has not crawled again till yet.
It is a new website and crawled for only once and that is in december 2007 since then it has not been crawled.
