If the generated text is mostly correct most of the time, people are just going to stop reviewing it because it's cheaper for them to waste someone else's time than it is to spend their own. Even those that are more diligent are bound to let things slip through the cracks because it's easy to lose concentration in a repeated, monotonous process. When everyone is doing it, it's not really a problem with a particular individual anymore.
