Anubis is a website protection system designed to safeguard servers from AI companies aggressively scraping content by implementing a Proof-of-Work scheme inspired by Hashcash. This mechanism increases the cost of scraping at large scales by adding minimal individual load, which aims to deter mass scrapers. Anubis is intended as a temporary solution while more advanced methods for identifying legitimate users, such as analyzing headless browser behavior, are developed. It requires modern JavaScript features, and users are advised to disable plugins like JShelter for proper functionality.
