It’s good sense, regardless of the jurisdiction of a specific Lemmy instance.

A jealous partner seeing the car where it shouldn’t had been is enough, isn’t it? Or the boss where the worker should had been elsewhere, or… Inhabitants of small districts also don’t need a license plate database to know.

Careful, mode 2 means reject all or fall back to accept all if there is no Reject All button. So use that only if cookies are disabled or otherwise controlled, for example by an AddOn like Cookie AutoDelete. If not, rather use mode 1 that hits only a Reject All button if available but ignores others.
