I ran into the private profile problem with bibliogram ALL THE TIME. Even tho I was friends with them on instagram. So I just stop using it. It was broken most of the time anyways. It was a fun 3rd party unoffical API frontend that I added to my list of other ones I could self host.
That amount of hostility to scrapping and 3rd party clients feels like that they want to be in control of the data not you.
