dont worry about this
There are sites from which backlinks are undesirable. It can happen that someone pays $10 for publishing an article and setting up a backlink so that it causes more damage than good. After that, it is necessary to invest more money to remove such a relationship. Without posting the website address, this is just hunting in the dark and these screenshots don't mean much, plus they can be faked.
So leave a link to the site so that everyone can do their own research, is it all worth the effort.
$10 for this service is a low price that raises suspicion, when we add to that your reputation here, everyone should definitely be careful with this offer.
