Unfortunately, I suspect such a search engine would start getting lawsuits about being uncompetitive once they start excluding sellers/spammers. Even if bogus, it's gonna bog things down real bad. They're good at abuse, it'd not be surprising.

I don't think it needs to include everyone unless it is a monopoly? (IANAL)

Of course, it could be inclusive, but each seller must prove their worth, and longterm sellers are always preferred.
