WordPress plugin swaps CAPTCHA for adaptive proof of work
What happened
On October 22 a Show HN post on the Hacker News front page introduced a WordPress anti-spam plugin that replaces CAPTCHA with a browser-side proof-of-work challenge. Visitors click nothing and solve no puzzle; the browser finishes the computation silently in a few milliseconds. The plugin covers login, registration, comments and WooCommerce, and supports form plugins including Contact Form 7, WPForms and Gravity Forms, with no API key or external service. An adaptive mode raises challenge difficulty automatically during an attack.
