The whole point is that the block isn’t about this particular user. Any affordable tool that can be used for anonymity, can and will be abused by malicious people. That’s why Tor is blocked on 90% of websites and why VPN users need to jump through extra hoops so often. If your network offers no way to distinguish you from the guy that keeps uploading videos of children getting raped, your network is getting blocked, simple as that.

For VPN users this is a minor issue, but for people behind CGNAT (which is the standard in many low-income countries these days) that causes huge problems.
