I think CloudFlare's security measures are insane. I use a VPN and I can tell which sites use CloudFlare because I consistently get a Error 520, where it claims the browser and CloudFlare are working, but the website is not responding. Yet I turn of the VPN and magically it works fine. That's dishonest. At least own that you are the one blocking my visit. I'm also developing with Dwolla's API, and CloudFlare blocks all HTTP requests from my local IP, so I can't develop locally. Thanks CloudFlare.
