Ofc Mohammed is the most common name but thats a name common within the muslim community. I have noticed the name Sarah in every country, regardless of race or religion. Or it might be an abrahamic religion thing but thats most of the world atleast.
I suspect other Abrahamic names might make the cut.
Or maybe the place is so infested that the moment a team raids a guy, they get counter-ambushed on the way out.
