Even when not on VPN, if a site uses the CloudFlare interstitials, I will get it every single time - at least the "prove you're not a bot" checkbox. I get the full CAPTCHA if I'm on a VPN or I change browsers. It is certainly enough to annoy me. More than Anubis, though I do think Anubis is also annoying, mainly because of being nearly worthless.
