As alucard said, we can investigate. But note well -- this is not for the sake of the webmaster. The submittal guidelines -- you and your affiliates were told right up front: DO NOT SUBMIT AFFILIATE SITES! and submittal of multiple "related sites" can (and that does mean "sometimes DOES") cause all related sites to be removed. We do this reluctantly, when the pain of the persistent spamming gets to be greater than the benefit to our users of listing the site. Note that this is the benefit of the surfer -- a site in a competitive market, that isn't very unique, has a very low benefit to the surfer, even if it has a high value to the webmaster. We consider ONLY the value from the surfer's perspective.
To protect yourself, when you are setting up a "distributed mirror site scheme" (also known as "affiliate spam"), you need to make sure that all of the involved parties know NOT to think about spamming the ODP, because for all practical purposes we will consider you the responsible party.
