Anubis Deploys Proof-of-Work Barrier Against AI Scraping, Raising Costs for Mass Bots

3 articles · Updated · MR Online · Aug 6

Summary

  • Anubis now presents a proof-of-work challenge page to visitors, aiming to shield websites from AI scrapers whose heavy automated traffic can trigger server downtime.
  • The system borrows from Hashcash-style proof-of-work: a small computational cost is negligible for individual users but compounds quickly for large-scale scraping operations.
  • Website administrators describe it as a stopgap while they build better bot detection, including fingerprinting headless browsers through signals such as font-rendering behavior.
  • Modern JavaScript is required to pass the challenge, and privacy tools such as JShelter may block it unless users disable them for the affected domain.

Insights

If headless browsers can solve Anubis, what stronger defenses will websites turn to next?
Can proof-of-work walls like Anubis really stop AI scraping, or do they mostly slow ordinary users while bots adapt?
