A developer has released a WordPress plugin that swaps CAPTCHAs for adaptive proof-of-work, requiring visitors' browsers to solve a small computational puzzle instead of clicking image grids. The approach aims to block bots while being less intrusive for users and avoiding third-party tracking services. The project is drawing attention among WordPress users and developers debating whether proof-of-work challenges can realistically deter spam without penalising low-powered devices.
