The problem with hosting with a company that has a track record of hosting PBNs is that it's only a matter of time until they get exposed.
That's the kind of situation you are in if you're rolling the dice going with PBN specialty hosting companies.
If I were you, I'd focus on finding mom and pop hosting outfits that are unrelated to each other.
Make sure that they are not just resellers.
The more distributed and diverse your network is, the higher the likelihood that your PBN will remain undetected.
That's the name of the game when it comes to PBNs: remain undetected.
If I were you, I would focus on building real websites and growing each of these websites into an authority site.
I think that is the way to go because that's the kind of strategy that would withstand the test of time.
PBNs, especially the way they are set up and managed, are simply too risky considering how fast Google is evolving.
