@distrowatch I faced ddos from all sorts of bots couple of months back when I started with a search engine. I ended up blocking 10K or so bots. If you want you can use it for your blocking/iptables/firewall: https://git.flossboxin.org.in/vdbhb59/hosts/src/branch/main/bots.txt

There maybe few false positives which I can delete if I am made aware of.
Hope it will help. #botsblocking #hosts #firewalls
