Seems to be doing something odd, code of the page includes some XmlHttpRequest to a blog site with randomized query string (see end of https://pastebin.com/W21Au8RK), along with some fingerprint library (though commented out)
That blog site loads very slow for me if I go there manually - maybe some kind of DoS being directed to it?
Seen this same faux-cloudflare page used on btdig.com too, with the same strange XmlHttpRequest & fingerprint code, pretty weird.
