Welcome to the AI future.
anthropic.com have been having bad press since last year and don't appear to care how much upset they cause.

Using Agent Headers or robots.txt is pointless as the aggressor cannot be trusted to be honest. I am currently looking for some form of proactive\reactive dynamic firewall blocking for this type of 'attack'.
I am also investigating if I can tarpit (without causing myself significant overhead) to actually slow down probes onto my network by causing heightened resource usage at the aggressor's end.

If you know of anything that may help please give me a head-up.
