You said, "suppose a fresh website has no PR or no link backs and automatically no of links reduced in 1 day!!!" but how is it possible to loss of backlinks if a site has no Nos of links, as you said. If you have Google Webmasters Tools installed for that site you can check it in your "link to the site" section.
Search engine frequently update their database with backlink websites have. If you are getting backlink from spam site, might be chance to lose those backlinks.... Imdad
