Their captcha page is odd, styled to look like Cloudflare's captcha gate but uses reCAPTCHA which Cloudflare publicly spoke about switching from.

Code of the page also seems to include a strange XmlHttpRequest to some 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.
