Why Websites Verify that I’m not a Robot?

Websites ask you to verify you're not a robot, usually through a "CAPTCHA" (Completely Automated Public Turing test to tell Computers and Humans Apart), to prevent automated programs (bots) from performing malicious actions like spamming, submitting fake forms, or accessing sensitive information, which can be easily done by a computer program but is difficult for a real person to replicate; essentially, it's a security measure to ensure only human users are interacting with the site. 

Key points about CAPTCHAs:

• Bot protection:

  The main purpose is to stop automated bots from performing actions like creating fake accounts, posting spam comments, or launching large-scale attacks on a website. 
• How it works:

  CAPTCHAs often involve tasks like identifying distorted text, selecting images that match a certain category, or solving simple puzzles, which are easy for humans but difficult for computers to do accurately. 
• "I'm not a robot" checkbox:

  Many websites now use a simple "I'm not a robot" checkbox that, when clicked, may trigger a more advanced CAPTCHA check in the background if the system suspects bot-like behavior.
