Not in my experience with FOIA requests. They likely have a process. Your request will be fulfilled either if they can't find a reason to deny it or if fulfilling it is easy for them. Since Facebook is making up a bogus reason and won't bulge, you need to figure out which regulator is responsible and contact them. Your snark is honestly impressive. However, if snark was going to work, it would have worked already. Facebook probably thinks that all you're going to do if they deny your request is reply with snark, so there's no reason for them to do anything in response at present. Words alone can't hurt them.

> Facebook’s current staff on this is on a higher pay scale than most.

What matters is who sets the policies for the company and the budget for the GDPR department, not how much individual employees who respond to the requests are paid. I doubt the people in the GDPR department set their budget and Facebook's GDPR policies on their own.

> I’ve made my mails impossible to ignore to the point of there being no plausible deniability; the entire GDPR department is aware by now.

I agree that Facebook's employees probably aren't ignoring you in the strict sense that they don't even read what you say. Maybe they forward your emails internally with comments like "Get a load of this guy!", but I don't think that's helping you. If anything, it hurts you because they have more people thinking of ways to deny your request.

> Given what you and others wrote above, it should probably be clear what real actions are going on behind the smoke and mirrors on my site.

If by this you mean that you've contacted a regulator or lawyer, good, I'm happy to hear that. I don't see a reason to hide that, however.
