A little bit more research showed that many other types of scams and spam content are hosted on x90x.net sub-domains. Here are a few of them:
Fake Google page
This site does not appear to be functional.
Links to Canadian Pharmacies
forex.com phishing site
Porn (no screenshot!)
and much more....
The hosting provider is also used by legitimate sites. It is very risky to host any important website with a free provider which is going to get abused over and over. co.cc has been blocked by Google Safe Browsing in the past, meaning all Firefox/Safari/Chrome users were prevented from visiting any of the websites hosted under co.cc. I believe that a $10/year domain name is really a must for any website. Do not rely on a free domain such as those provided by x90x.net that could soon be on Google's and others' denylists.
