Allow and refuse lines
This agent has no robots.txt token, so there are no lines to copy. Without a token, a published list or a signature, a site owner cannot tell it from an ordinary visitor by request alone.
Refusing or allowing in robots.txt states a preference. Enforcement of a refusal belongs in your WAF; see how to verify the identity above.
