Not sure if this is the same kind of "endless loop" that I've experience on the Cloudflare captcha page; while on a VPN, the only way I can get past the "I am a Human" captcha is to refresh the page and click the area where the checkbox appears as fast as I can with my mouse before it even appears. It might take two or three tries, but it hasn't failed yet.

I have no idea why this works so well, but I haven't found another way (other than getting off of my VPN) to get past this screening page.
