I'm curious how you think that it's related. A blacklist directly impacts the startup purchasing the domain from purchasing it because of the murky ground involved in removing a domain name from blacklists.
And then, if you have a clear-cut mechanism for getting domain names off a blacklist when they cease to be squatted, what's the point of it? Domainers don't tend to build websites on theses domains, so blacklisting them out of being indexed on search engines is simply fixing a problem that doesn't exist. And as such, it doesn't lower the projected value of the domain in the eyes of either the purchaser or seller.
So it's not clear what purpose a URI-dnsbl would serve in regards to domaining.
