Eh? With the "anonymous" models that we're pushing for right now, nothing stops you from handing over your verification token (or the control of your browser) to a robot for a fee. The token issued by the verifier just says "yep, that's an adult human", not "this is John Doe, living at 123 Main St, Somewhere, USA". If it's burned, you can get a new one. If we move to a model where the token is permanently tied to your identity, there might be an incentive for you not to risk your token being added to a blocklist. But there's no shortage of people who need a bit of extra cash and for whom it's not a bad trade. So there will be a nearly-endless supply of "burner" tokens for use by trolls, scammers, evil crawlers, etc.
