I have seen bought some services in the past from sellers who dint not provide reports of what they delivered. They promised home page Obl of 25 for their PBN. But when i discovered the links in ahrefs to my surprize there was obl of 50 and still increasing. In my view point seller who do not provide reports for the sake of so called safety of their cliets blah blah...have always bad intentions. They still say you will see links in ahrefs or webmasters. Otherwise what is the issue a genuine customer knowing or discovering thier kohinoor like network. I think they believe google id sending decoy customers to find their network.
