Careful. It’s iNaturalist who automatically hides casual observations. You know nothing about what users who provide IDs would do if captive observations were shown to them by default.
There have been many calls in the past to change this (https://forum.inaturalist.org/t/make-captive-cultivated-not-automatically-no-id-needed/112 is an example, but you can find so many others). As long as this doesn’t change, you can’t fault users to make the best of the situation they find themselves in.
