We outsmarted CSGO cheaters with IdentityLogger

For UT2004, you can ban by player GUID (a hash of the CD key) or IP. With the game abandoned by Epic, a number of key generators have cropped up, which makes GUID bans useless. IP bans only go so far with VPNs costing $2 these days.

The main solutions we have today are IP ban + VPN blocking using a database of known VPN subnets and adding them all to the firewall, and a similar fingerprinting technique which scans their folder structure of certain system folders.

No. VPN blocking is useless to stop malicious actors as most residential connections have DHCP and VPN subnets are added and removed somewhat frequently, it's not that hard to find a "undocumented" one. It also completely excluds anyone using a VPN for non-malicous purposes.

Scanning files and folders is just ridiculous, not only an incredible invasion of privacy, but also trivial to work around.

Excluding someone on VPN from playing UT2004 on a specific server is not an abuse of their human rights

where was the parent mentioning this is a violation of one's human rights exactly?

Privacy is a human right.

Not when you are willingly connecting to a server. The server owner didn't force you to do it.
