I'm split here between saying "Doesn't mean you need to make it easy for them." and "How 'interesting' must a completely anonymous account look inside FB?"...
It's very hard to say, and I would imagine it's hard to say even for the average Facebook employee too, given how large the company is. If it was a single coherent entity with its own knowledge map (which, last I checked, it still isn't, but I will check again in 2022), we could probably reason differently about it though.
