Each individual proof is zero knowledge, but downloading a _bunch_ of them is an indicator, yes. There's no real way to work around this with the current ZKP scheme. I'd argue ZKP is, in theory, the least worse option of all current age verification scheme.

My personal opinion is that age verification itself is a bad idea, but if we're going to go ahead with it, I'd much rather we use ZKP for it than the current mess of "upload your passport and picture of yourself to dodgy 3rd parties that likely now have your browsing traffic associated with your real name"...

So the government would impose a maximum limit on the number of porn sites you can visit each day?

Not necessarily, but it would be difficult to justify why you need to access 1000 porn sites every day, I guess?

The point is that if you build a service that sells age verification tokens, you are doing something illegal. And if you start doing something illegal by gathering said tokens with your own identity, maybe it's not the most clever way to do something illegal?

		So the government would limit me to accessing only 999 porn sites a day? Is it going to be like structuring law, where it's illegal to access 1000 or more but it's also illegal to avoid accessing 1000 or more by accessing a lower number?
