Ask HN: Scammer Using an '\@Meta.com' Email?

This person officially has his workplace at the recruiting firm, but I don't understand why he'd have a meta email address. I would expect him to have the recruiting firms email. Unless meta gives third-party recruiters top-level domain email addresses, it's super odd. My guess is someone at meta has been compromised, but I could be wrong and just paranoid; perhaps it's legitimate (super skeptical, though).
