PUBLIC MARKS with tag captcha

Stop more bots. Start protecting user privacy. Do you use a captcha to keep out bots? hCaptcha protects user privacy, rewards websites, and helps companies get their data labeled. It is a drop-in replacement for reCAPTCHA: you can switch within minutes.

Since the launch of No CAPTCHA reCAPTCHA, millions of internet users have been able to attest they are human with just a single click. Now we're taking it a step further and making it invisible. Human users will be let through without seeing the "I'm not a robot" checkbox, while suspicious ones and bots still have to solve the challenges. We’re excited about this and hope you will give it a try!
