How would they know? The point of returning “standard” values, is that you are indistinguishable from any number of legitimate users.

They start blocking any fingerprint that looks like you're hiding it. Similar to sites blocking known Tor exit nodes and proxies.

The point is that the fingerprint looks like “the generic fingerprint”, blocking that would be pointless, because it’d block a massive number of completely valid users.

It doesn't have to be blocking fingerprint, just whatever garbage data that works and the cat/mouse game will continue as usual.
