CAPTCHA prevents bots from automatically submitting your form. These web bots are programs that leech through the web pages. When it finds a form, it fills the form with a spam message and submits it.
Captcha also offers custom ads with your slogan instead of random letters and numbers.
There’s “slide to fit” and “cost per type” (customers type in your brand or slogan to “engage”).
