Because Facebook’s data practices, and how much was volunteered by users on there, means that for some percentage of trans users Facebook knows that they’re trans. And you also have a percentage of pregnancy photos uploaded, if someone identifies as a woman on Facebook, and has uploaded photos with a baby bump, she’s cis (or at least a pre-hatching trans person). And at one point in time, a lot of people just volunteered that info to Facebook.

Yeah, but the training set is nowhere near clean. That’s my point. “Close” is no where near good enough within this context,
