Everyone. Just search their name and select the correct personality from the list (based on zip code and age). People can, since a few years ago, see who has viewed them, which deters it a bit. But easy to just have a friend or something look up your coworker or boss if so.
Also, media gets everything and make lists. "This is what the soccer players make", "top 50 influencers" etc.
I don't think it's abused much. For wealthy kidnappings and so it's easier ways than to brute force names of potentials. Instead just look for CXOs or owners of companies that are doing ok (also public data). Refusing tenants with low salary is already done through credit agencies all over the world, this doesn't change anything in that regard either.
As for privacy: I guess you could say so. But as I said, it's part of the culture so I don't feel most people mind, and it helps us to get paid fairly.
