No webmasters want their website to fall into the pit of Google. Once booted by Google it’s really hard to reinstate a website. The two common worst scenario you would encounter with Google is sandbox and website ban. You don’t want to end up to either of these. Sandbox process could take up to 6-8 months, which could be against your plans causing frustration to webmasters. The best thing to do if you’re sandbox is to build a better linking strategy so that the Googlebot spider would find your pages easier while it’s in the sandbox instead of repeatedly submitting your website every time. If you’re banned by google you better go to this section google.com/webmasters/ then make a reinstatement.
