Making Sense of Anubis: The Web's New Shield Against AI Scrapers

You're seeing this message because your web browser has detected that you're not human, and the administrator of this website has set up Anubis to protect their server from the growing threat of AI-powered scrapers. While it may seem like a hassle, this measure is essential in ensuring the long-term sustainability of online resources.

So, what exactly is Anubis? In short, it's a compromise between security and user experience. Developed as a response to the increasing prevalence of AI-driven scraping, Anubis employs a Proof-of-Work scheme similar to Hashcash, which aims to make website scraping more expensive at large scales while allowing individual users to bypass the challenge with minimal impact.

The concept is simple yet ingenious: by requiring users to complete a small computational task (the "proof of work"), Anubis creates an additional barrier for malicious bots and scrapers. However, at individual user levels, this added load is barely noticeable, making it an effective solution at the scale required to counter the AI-powered scourge.

But there's more to Anubis than meets the eye. Its real purpose goes beyond mere security; it serves as a placeholder solution to give developers time to refine their fingerprinting and identifying techniques for headless browsers (think bots that render web pages without user interaction). By testing this "good enough" measure, researchers can better understand how these malicious agents behave and develop more targeted countermeasures.

However, Anubis does come with some caveats. For instance, it requires the use of modern JavaScript features, which plugins like JShelter often disable to prevent website scraping. If you're using such plugins on this domain, please consider disabling them for Anubis version 1.20.0 to access its challenge page.

Keep in mind that enabling JavaScript is a requirement due to the evolving social contract around web hosting and AI-powered scraping. While a no-JS solution is still under development, it's essential to respect these changes to maintain website security and integrity.
