The blog darknetone is know to be unreliable. Like
most of websites on the clearnet posting .onion urls because it very often leads to fake sites imitating real ones. You can check about DarkFox Market for exemple, the URL is also wrong.
Most of the blogs related to bitcoin mixers have phishing URLs. And ranking them up in the Google SERPs is not as hard as you think.
The thing with the mixing industry is it's a small niche with not a lot of competition. Hence, not a lot of blogs related, hence any garbage can be in the first page. You can even see hacked websites selling clothes for kids ranking in the first page of google when you search for "bitcoin mixer xxxx"
Believe me, I crawl a lot the SERPs and spy them (including their strategies) there are a lot of shits. I got once an idea to become their nightmare and make them lose money (or rather to prevent victims from losing their money). Or at least to make a blog to be "annoying".
People running mixers could also share about the threats they receive, it could be fun to read
