Is there anyone here use PBN?

[sansastark]

Nice day my friends,

I'm in the amazon affiliate niche business and I've been reading up PBN. Why not just use the expired domain with high PR/DA etc and as the affiliate site instead of using it as a pbn. I'd still be able to rank very well, no?

When building a personal PBN I've seen multiple resources when searching the web that say you can host your PBN websites on the same server IF you use a CDN such as cloudflare, which "Mask" your actual name servers and IP,

now, for the sites I run they operate on completely different machines ran by totally different companies, however, is this CDN statement true?
