Contact Form 7 Image CAPTCHA, WPForms Image CAPTCHA, Form Spam Image CAPTCHA, GDPR: Breakdown
The Contact Form 7 Image Captcha plugin works by inserting a CAPTCHA – a small, automated test designed to tell a human from a computer – at the end of the contact form on the website. This plugin works as a security measure to protect the website from bots trying to use the contact form to spam or abuse the website in some way. The plugin features a CAPTCHA image with randomly generated characters, so that any advanced bot will not be able to figure out what the characters on the image are.
The plugin is designed to seamlessly integrate with the existing Contact Form 7 plugin and offers various settings that can be configured by the website owner. The owner can decide on the size of the CAPTCHA image, the actual CAPTCHA characters used, the font used on the CAPTCHA, and other customization options. This makes it one of the most powerful and customisable CAPTCHA plugins available.
The Contact Form 7 Image Captcha plugin also allows for ‘confirmation’ and ‘blacklist’ settings, where specific words, phrases or email addresses can be blocked from accessing the contact form. This extra level of blacklisting helps prevent unwanted spam from clogging up the contact form.
The plugin is also user-friendly and designed to be accessible for people with disabilities. It offers different styling options for different types of users, such as larger text and a different colour palette for users with vision impairments. It also offers a high-contrast version of the CAPTCHA, as well as an audio CAPTCHA for people with hearing impairments. This makes it one of the most comprehensive CAPTCHA plugins available for websites.
