Summary

The BAILII website anti-bot protection system (Anubis) triggered a challenge page when attempting to access an ECHR case. This is a proof-of-work barrier designed to block automated scraping by AI companies. Users must solve the challenge to access the underlying legal content.

What changed

The BAILII Europe Recent Decisions page for this ECHR case was blocked by the website's Anubis anti-bot protection system. Anubis implements a Hashcash-style proof-of-work challenge to make mass scraping by AI tools more expensive and resource-intensive. The page notes this is a temporary solution while more sophisticated headless browser detection is developed.

This is a technical access control measure, not a regulatory action. Legal professionals and researchers seeking access to ECHR case law will need to either complete the proof-of-work challenge or disable browser extensions that interfere with JavaScript execution.

What to do next

  1. Complete the proof-of-work challenge to access case content
  2. Disable JavaScript-blocking extensions like JShelter for this domain

You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites. This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.

Anubis is a compromise. Anubis uses a Proof-of-Work scheme in the vein of Hashcash, a proposed proof-of-work scheme for reducing email spam. The idea is that at individual scales the additional load is ignorable, but at mass scraper levels it adds up and makes scraping much more expensive.

Ultimately, this is a placeholder solution so that more time can be spent on fingerprinting and identifying headless browsers (EG: via how they do font rendering) so that the challenge proof of work page doesn't need to be presented to users that are much more likely to be legitimate.

Please note that Anubis requires the use of modern JavaScript features that plugins like JShelter will disable. Please disable JShelter or other such plugins for this domain.
