Auditing sure, but almost any Facebook software engineer has permission to still take super user actions. The ability to abuse is still there, it's just a question if they actively audit well enough to catch the abuse.
Not sure if you can share more, but this seems way to easy and auditing is, well, to late.
I never worked in a role that required me to go further, but the penalty of losing my job deterred me just fine.
If this is true, I find it shocking in light of all of the recent allegations especially.
