Until Cloudflare decides to not even serve you the CAPTCHA because your browser is too old. Where "too old" can mean the current Firefox ESR release, or a small niche browser. Or it legitimately is an older browser because you're into retro computing preservation. Cloudflare position themselves as the internet safety police will turn the web into a monoculture and that was the argument used against MSIE and now used against Google. But this is a larger threat because the end-users don't choose to use CF so it isn't measurable how many people are being adversely affected. Site owners' metrics will only show them the permitted users and they'll be unaware that their applications are unusable to many people. How do you get a bug report from something that doesn't appear in your logs?
