I'm getting a guest post on a website with a PR5. The site has 20 links pointing to it and 0 re-directs from other domains (looked at Ahrefs). I checked and the PR is valid. I looked into WHOIS data and the website domain was only created since Feb. How the HELL can you get a PR5 domain on a 2 month site? I looked at the posts and they go back to 2011. Any thoughts as to whats going on here?
