The Liabilities of Robots.txt (2503.06035v1)

Abstract: The robots.txt file, introduced as part of the Robots Exclusion Protocol in 1994, provides webmasters with a mechanism to communicate access permissions to automated bots. While broadly adopted as a community standard, the legal liabilities associated with violating robots.txt remain ambiguous. The rapid rise of LLMs, which depend on extensive datasets for training, has amplified these challenges, prompting webmasters to increasingly use robots.txt to restrict the activities of bots engaged in large-scale data collection. This paper clarifies the liabilities associated with robots.txt within the contexts of contract, copyright, and tort law. Drawing on key cases, legal principles, and scholarly discourse, it proposes a legal framework for web scraping disputes. It also addresses the growing fragmentation of the internet, as restrictive practices by webmasters threaten the principles of openness and collaboration. Through balancing innovation with accountability, this paper offers insights to ensure that robots.txt remains an equitable protocol for the internet and thus contributes to digital governance in the age of AI.
