A developer released a WordPress plugin that replaces visible CAPTCHAs with a silent proof-of-work challenge, requiring visitors' browsers to solve a small cryptographic puzzle before submitting forms. The plugin claims to work across logins, registrations, comments, WooCommerce checkout and major form builders like Contact Form 7, WPForms and Gravity Forms by recognizing submission signatures rather than relying on per-plugin integrations, and it offers a manual mode to learn custom or unsupported forms.

The article's page itself was blocked by Anubis, a proof-of-work tool websites deploy to deter aggressive AI scraping bots, illustrating the very problem the piece discusses. Anubis forces browsers to solve a computational puzzle before loading content, adding negligible friction for humans but real cost for mass scrapers.

Anubis, a proof-of-work challenge system designed to block aggressive AI scrapers, has finally shipped a WebAssembly-based version after roughly a year of development. The tool works similarly to Hashcash, forcing browsers to solve a computational puzzle before accessing a website, which is negligible for individual users but costly at scraper scale. Site administrators use it as a stopgap measure while better methods for detecting headless browsers are developed.

A hobbyist bought two ASRock BC-250 mining cards from AliExpress for £126 and £103 respectively, and successfully unlocked all 40 compute units on both despite AMD's binning meant to disable some cores. One card also unlocked all 8 CPU cores, while the other had one faulty core, but both performed well running the gpt-oss-20b language model via llama.cpp, hitting up to 100 tokens per second at 8K context.
