XCheck at Meta: Why it exists and how it works
It makes sense from a technical perspective why you'd build a system like XCheck. The problem is that once you build XCheck you actually need to say to your C-suite and PR department "Actually no, you can't say we treat everyone equally, we're manually going in and exempting certain people from scrutiny, and that's entirely within our discretion."The problem isn't technical, it's legal - you can't build a system that operates one way and then publicly misrepresent it.
