It's ironic as this vandalism was spotted and reverted in less than 24 hours in OSM. So any improvements and community fixing of vandalism cannot be taken advantage of by Mapbox if they rely on a monthly snapshot.
You'll still need some way to deal with ongoing edit wars -- I'd imagine the mapping of Jerusalem to be prickly, for example. But at least you can tell that content is dangerous and direct your human review in that direction.
Even better, less than 2 hours.
