I'm not up to speed on exactly how spam filters blacklist domains but I strongly suspect if Gmail thought spam was coming from email.facebook.com then it would restrict facebook.com too. That's the only reason I can think of for creating such a clunky domain; it's that a neater looking sub domain won't avoid the problem - hence having to register something completely different.
That sounds like a preference that would be added by whoever configured the server rather than anything else. I've definitely seen situations where a third-level domain has been under the control of (or sold to) a third party and so it wouldn't make sense to block the second-level, or other third-levels branched off from it if only one third-level misbehaved. Edit: And I don't just mean countries that treat second-level as top-level for some uses, like, say .co.uk.
I have no idea what the defaults are for various automatic spam blockers, since both arguments have merit.
