This appears to be a simplistic attempt at link manipulation, with the owner/operator of the site registered in the clear using the one privately registered as a source for IBLs. However, as Google is a Registrar, and thus has access to data not publicly available, and as the Registrar of the privately registered DN has the identity of the real Registrant on file, Google may be able to detect such collusion.
