As a happily employed engineer who has FAANG recruiter friends and gets scouted fairly regularly, I think you also forgot "and is willing to jump through the hoops you put in front of them".
Also, this doesn't sound like it needs to be an engineering problem. A customer support team could alleviate the workload. Even if its an internal-only, non-public support team, just people whose job it is to do the manual data scrubbing.
This sounds like a possible revenue opportunity as well. People would probably pay for the ability to ensure accurate data for their Places, which could also serve as a way for G to ensure the Place data is valid and meets their editorial guidelines. Don't know if this already exists or not but it sounds like it should.
