I saw that site is a Russian site.
My idea is that the script there is normal Russian text just "encrypted" a bit:
The consonants were replaced by non-equivalent or non-similar latin consonants and the vowels were also replaced by non-equivalent or non-similar latin vowels.
I did not take the effort to prove my theory so I am waiting for some eager beavers to do so
Btw imo nothing secretly is stated is on those pages.
