Cloudflare Introduces Continuous Accountability System for Verified Bots
Key points
- Cloudflare introduced a system for continuous bot behavior evaluation.
- System assesses if Verified Bots respect site preferences and feedback.
- Trust is measured by consistent behavior, not just initial identity.
- Perplexity's bot was delisted in 2025 for ignoring opt-out requests.
Continuous Evaluation for Verified Bots
Cloudflare has rolled out a new system designed to continuously evaluate the behavior of its Verified Bots. This initiative moves beyond initial identity verification to focus on ongoing trustworthiness, addressing the question of whether a bot can be trusted based on its actions over time. The system aims to ensure that Verified Bots consistently adhere to expected standards of conduct.
Defining Trust and Risk
The new system distinguishes between 'risk' and 'trust'. Risk refers to the likelihood of a single request or action being harmful, which can change moment-to-moment. Trust, conversely, is built through repeated and consistent behavior over time. For a bot to remain Verified, it must accurately identify itself, perform only its stated functions, and refrain from abusive behavior.
Monitoring for Abusive Behavior
A core component of the system is monitoring for abusive behavior, particularly regarding respect for site preferences. This includes whether crawlers ignore requests to not crawl or to slow down. Cloudflare developed metrics to measure how often a bot respects these preferences, translating observations into an 'explainable trust band' that indicates consistency and informs assessment.
Key Evaluation Signals
Initial signals evaluated by the system include whether the bot respects instructions and if it responds to direct feedback from websites. These are considered fundamental 'common sense' rules for bot etiquette. An example cited is the delisting of Perplexity's bot in 2025 for attempting to access opted-out resources and circumventing controls.
