Unacceptable, sorry this is happening. Do you know about fail2ban? You can have it automatically filter IPs that violate certain rules. One rule could be matching on the bot trying certain URLs. You might be able to get some kind of honeypot going with that idea. Good luck

They said that it is coming from different ip addresses every time, so fail2ban wouldn't help.
