@Sgt_KickAxe:

...it's preferential treatment to the undetectable spam sites.

Can you elaborate on how they are undetectable?

Their incoming links aren't paid but they sure can leverage discovery properties.

Would you mind elaborating on what you mean by "leverage discovery properties"?

Thanks in advance.
