I can't speak to Facebook's intentions or policys(I don't use big blue app at all), but many sites use tools like Full story to discover bugs or watch a customers user journey to discover flows that aren't working well. Some portions of the page are automatically filtered(inputs with type=password), and the rest depends on the team being very thoughtful about marking sensitive portions of the screen as such.

It's a very manual process, but probably one of the most powerful tools for improving user experience I've ever seen. And typically for most businesses, you are keeping these sessions for 2 weeks or thirty days at most.

I absolutely agree - I used something similar at my previous job.

But neither of us know Facebook's policy (although we can easily guess their intentions, based on past behavior), and nobody ought to be expected to cut them any slack.
