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."<p>The problem isn't technical, it's legal - you can't build a system that operates one way and then publicly misrepresent it.
