1) That would only be the floor of where it might go. They could easily ask for more.
2) I worry this profiling system for porn site usage will hit far more legitimate usage (false positives) than it would any "nefarious usage". It's hard to imagine a porn site is a particularly good avenue for pursuing child porn photos reliably, especially a lot of it. This smells of religiously motivated lobbying.

4) Age verification for porn sites impinges on freedom of expression and privacy. This feels very moral panicky, a scientifically dubious moral panic (https://qoto.org/@olives/111083302650803082).
