OP gave me 1 link from one of his sites in the network. The domain had keywords in it. I am not a great fan of metrics but I check the referring domains of my backlink providing domain. I found 50+ RD with many decent domains pointing to the PBN site.
Well themed and PBN built with effort. The article passed Copyscape though readable but hey it’s 5 bucks per link, so I don’t expect to see a handwritten article anyway.
From my experience, casino sites are generally known to have spammy backlinks, however to my surprise, I find this domain to have a clean backlink profile, which is a huge plus for a casino PBN network.
