even with an equivalent volume of PRs, code reviewers *must* use heuristics to judge how much effort to pour into any given line of code. what's the contributor's reputation, do you trust them to know what's going on, what's going on in this file, is this a tricky area of the code, are there subtle mistakes to look out for. spambots flatten the probability of a mistake into a uniform statistical distribution instead of following human patterns
so you have to be equally vigilant on every single line of code, which is way harder than you think (even if you already know that it's pretty hard). and you have to exercise that level of vigilance *because* the contributor didn't care enough to pay attention to the code themselves. it is a recipe for burnout.
