Any system that grows too fast has these kinds of problems. When it's a small intimate circle where everyone knows everyone, reputation alone can keep people in check. Once it's larger you need to invent rules and bureaucracies and structures and you will have loopholes that bad actors can more easily exploit, hiding in the crowd, than in the small version. It's the same with the Internet or computing. Security was much less of a topic when it was mostly honest academic nerds using the Internet, and the protocol designs often didn't even assume adversarial participants. Science also still runs on this assumed honesty system that worked well when it was small.
