Have you thought about that beyond your knee-jerk reaction? One of the primary reasons for using cloudflare is resistance to denial of service attacks, and you want cloudflare to helpfully publish the real IP of the server CF is proxying for?

Scammers, thieves, phishing, and cybersquatting are weak or nonsensical reasons for demanding that CF reveal the IP they're proxying for. If a site is breaking the law, use the legal system to request the real server IP from cloudflare.

I suppose you're also against Tor, because it cloaks client-side evildoers like CF cloaks server-side evildoers?
