Some thoughts on how useful Anubis really is. Combined with comments I read elsewhere about scrapers starting to solve the challenges, I'm afraid Anubis will be outdated soon and we need something else.

Cloudflare would need https keys so they could read all the content you worked so hard to encrypt. If I wanted to do bad shit I would apply at Cloudflare.

Maybe I'm misunderstanding what "behind cloudflare" means in this context, but I have a couple of my sites proxied through cloudflare, and they definitely don't have my keys.

I wouldn't think using a cloudflare captcha would require such a thing either.

That's because they just terminate TLS at their end. Your DNS record is "poisoned" by the orange cloud and their infrastructure answers for you. They happen to have a trusted root CA so they just present one of their own certificates with a SAN that matches your domain and your browser trusts it. Bingo, TLS termination at CF servers. They have it in cleartext then and just re-encrypt it with your origin server if you enforce TLS, but at that point it's meaningless.

Oh, I didn't think about the fact that they're a CA. That's a good point; thanks for the info.

Hmm, I should look up how that works.

Edit: https://developers.cloudflare.com/ssl/origin-configuration/ssl-modes/#custom-ssltls

They don't need your keys because they have their own CA. No way I'd use them.

Edit 2: And with their own DNS they could easily route any address through their own servers if they wanted to, without anyone noticing. They are entirely too powerful. Is there some way to prevent this?
