www.screensaver-maker.org is considered to be a deep link of
www.shareware4web.com. That is, we consider screensaver-maker.org to be a part of the site of shareware4web.com, even though they have different domain names. The ODP definition for a "site" is somehwat flexible, since we consider domains like
Geocities.com to host thousands and thousands of sites, even though it's only a single domain name. And in our definition for "site", a single site can be spread across multiple domains, in which case a link to a one of those other domains would be a deeplink, which we don't list (unless there's some compelling reason to list it).
Additionally, the maker of the software,
21hua.com, is already listed, so there's no particular reason for us to list another site whose only purpose is to sell the exact same software.
