If it’s a hobby to you and no intention of making money online so the penalize site is ok and you care not for Google, but if your unto money making once Google penalize your site forget it its only a waste of time to continue developing that site or promoting that unless if you want to promote it via YouTube or facebook or adword or any PPC method. it’s really easy to recognized a site that are being penalized. if you notice your site with your target keyword nga naa siya sa first page or second page then later on or tomorrow you find out that it jump to page 200 dang that is a serious threat to you , so once you experience that, you have to try building quality link like buying a side-wide backlink to high pr site. if you can see the progress then its not penalize but if its not moving then its already doom .
Value well if you can make money with the site it still has a value but if its only an expenses then forget it .
