Sigh. We changed this so long ago yet people repeat this over and over again. Do you use the Tor Browser? Please show me a site on Cloudflare which uses CAPTCHA on Tor.
I don't know about TOR, but a couple of years ago we had a site on Cloudflare that had the CAPTCHA come up for visitors from mainland China - where the great firewall blocked the requests to Google. Chinese users were effectively locked out. We contacted Cloudflare about this and got dismissive replies.
