Captcha works fine I assume. However, since around August of last year, cloudflare made a change to their captchas and whatever you'd like to call it. As VGMoose mentioned, the cookies ain't persisted, I was told by a developer offsite that Switch Users can't see the cloudflare verification checks after you click the box because the browser is missing a cookie Cloudflare captchas runs off of.
A couple weeks ago the spam method was working, just spam click the check box on your cloudflare captcha and you should get verified. This only works for the smaller sized captchas from my understanding, the captchas you get when you enter website that says "Checking that you are not a robot" is a it more tricky and advanced.
I heard Cloudflare got an update so I don't know if this still works!
