@Domain-Matty Thanks Matty! This cheating is the core of the guest posting business. Unfortunately, Google hasn't come up with any penalty for this. People are buying domains with high DA authority and making them guest blogging websites to earn $10 to $50 per post.

It's fake. Usually, people who don't know about SEO and link building try to get the link built for the website using people from Fiver or other online Facebook groups to increase the DA (Domain authority) of the website. They charge you a few dollars and post your website to the redirect links like this. This may increase your website's DA, but if you check the website traffic, it's hardly reaching 2000 visits per month. Also, Google doesn't consider this MOZ DA to increase your ranking. This is usually done to steal money from some newbies and that's it.
