I think no matter how you slice it though, it's unethical and reprehensible to coordinate (even a shoddy) DDoS leveraging your visitors as middlemen. This is effectively coordinating a botnet, and we shouldn't condone this behavior as a community.
It's definitely interesting to see this roll around since the only individuals that see the CAPCHA page mentioned, are users of Cloudflare's DNS services (knowingly or not).
P.S. Shout-out to dang for dropping the flags. I have a small suspicion that their may be some foul play, given the contents...
I use my ISP's default DNS servers and have consistently gotten the CAPTCHA page for weeks now. The CAPTCHA seems to be broken too, rendering archive.today entirely inaccessible.
