The image captcha displays an image with distorted characters that the user must enter correctly to prove they are human. The math captcha presents a simple math problem that the user must solve to gain access to the site. The Google reCAPTCHA is a more advanced captcha that uses machine learning to determine if the user is human or not.

You can customize the size and color of the captcha, as well as the font and background color. Captcha Plus also allows you to add your own custom CSS to further customize the captcha’s appearance.

Compatibility with Contact Forms

Captcha Plus is compatible with a range of popular contact form plugins, including Contact Form 7, Gravity Forms, and Ninja Forms. This means that you can easily add captcha protection to your contact forms to prevent spam and automated bots from submitting fake entries.

Block Spam by IP Address

Captcha Plus also offers the option to block spam by IP address. This means that if a user repeatedly submits spam entries from the same IP address, Captcha Plus will automatically block that IP address from accessing your website.

Statistics and Reports

Captcha Plus provides detailed statistics and reports on the number of captchas served, the number of successful and unsuccessful submissions, and the number of blocked IP addresses. This information can help you to identify patterns and trends in spam activity and take appropriate action to prevent it.

Captcha Plus can help to prevent spam and automated bots from submitting fake entries and clogging up your website with unwanted traffic.
