> There's no way to implement this without (1) usage-based profiling (what's being banned in the first place) or (2) ID verification.
(3) zero knowledge age verification hosted by the gov which already has all the data anyways
for my taste that goes a bit too much into "you don't have anything to hide" and doomerism. if one wants, one can boot a TailsOS with a VPN and then no, the gov does not have all the data it needs to link it to you. just because lots of stuff is being monitored we don't have to destroy every privacy boundary in existence.

by "zero knowledge" you of course mean "the government can shadowban you without your knowledge" ?
Edit: non-snarky response: what's the default "fall-back" if government's signature is missing? IMO any option ("tracking/no tracking/invalid request") will be exploitable in bad ways.
