Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

Overview
About this plugin
ZigZag Image Captcha for Contact Form 7 adds a powerful, image-based captcha field designed to protect your forms from spam and bots.
The plugin generates a zig-zag distorted captcha image with background noise, dots, lines, and randomized angles — making it extremely difficult for automated bots to solve.
