I maintain a list of
"23034 IPs to blocklist.txt"
blocked IPs they contain all VPN providers. Often VPN providers seed Geofeeds with wrong data, this is why i use traceroute and ping network to locate their real location.
I have a script that logs IPs for any traffic coming in to my servers on ports that don't accept traffic. I then block those IPs from accessing ports behind which there are services.
If they're checking my locked doors, I don't want them coming in my unlocked doors.
This might be a good idea, but consider banning them for, say, a couple hours at a time. It’s easy to rotate IP, especially if you’re using a residential proxy service, and there’s a good chance you’ll end up blocking real users using the same ISP.
yeah, I'm using https://proxybase.xyz for this. It's like Mullvad but for proxies. No kyc, no email but supports xmr.

That’s nice, I need to implement this.
Closed ports are not "locked doors", and open ports are not "unlocked doors"
That is a binary thought process with a lot of assumptions. You might introduce even more attack surface in pursuit of this "security" measure by installing additional software like fail2ban, for example. Close your ports, maybe assign a non-standard port to the popular ones (like SSH) to reduce log spam, and patch your server often. Anything more complicated than that is not worth it, IMO.
You know that people use VPNs for perfectly legitimate reasons, right?
Like when I was travelling, sites would routinely use the language of my IP address location, not the language preference as I set it in my browser. So I would be served a site that I couldn't read. My only option was to use a VPN to spoof my location so that it would serve me a site in a language I understand.
By the way, if you’re a webmaster doing this, look at the Accept-Language header instead: https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/...
I use aVPN when I’m traveling and want to order food delivery for my 93 year old mother in NY. UberEats and InstaCart will stop me from ordering when logged in my mom’s NY account if I’m in China, Saudi Arabia, India, Vietnam, etc.
yeah, I know the pain...Refer my comment above.
