> hundreds of requests per day

Does this matter? I can handle hundreds of requests per day with no issue on a home cable modem connection and my desktop pc running nginx. In fact I do and have since the 56k days. With an actual server or VPS with a big pipe in a datacenter this should literally be below noticing in terms of cost.

I would characterize this response to normal public website traffic as more harmful than the "problem". There's no need to be upset that web spiders are visiting your public website. That is what public websites are for.

Anyway, if you really do want to persue this silly thing start by looking up the ASN the IP is in and go from there. Don't rely on cloudflare to interpret the internet for you. I wrote an offline geo-ip and whois db dump world map visualizer in 2025 and these are the resources I use:
