By your nick I would guess your an affiliate guy. Do you make sites for the sole purpose of getting adsense and affiliate money. G is on a rampage right now banning these types of sites. If your site is pretty much just thousands of landing pages made from word tracker info and your content is randomly generated and/or you have a scraper site then your site has been hand banned. G is taking spam reports serisouly. It's kinda cool. The spammers are all turning each other in and eventualy everybody will be gone.
