Feature summary (what you would like to be able to do and where):
Turnstile is Cloudflare’s smart CAPTCHA alternative. It can be embedded into any website without sending traffic through Cloudflare and works without showing visitors a CAPTCHA.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
Blocking spambots. ReCaptcha are cracked long time ago. And seems like hCaptcha also cracked (but not widely like ReCaptcha) as we're getting spambots every month since summer.
Benefits (why should this be implemented?):
- Easy to implement.
Cloudflare provides "compatible" mode of ReCaptcha. It's likely replacing two or three lines. (but <noscript>. seems they didn't support it)
- Another Alternative of Captcha. From a company that has at least minimum "trustable" reputation. (In my opinion.)
Note: Compatible mode seems requires ReCaptcha v3. Which is not implemented. See T208829.
