Being a fan, I wanted to follow the link to see what was going on. When I hit the site for the first time, a "cloudflare" captcha page popped up and had the check box you would click then you would normally complete the captcha. Instead, after clicking the captcha box, another thing popped up on the page telling the user to press windows + r, then copy and paste the text shown in the included image to verify that they are a human.
