The moderation was a lot of the problem, but not the whole problem. Honestly these days a larger part is that old, low-quality answers are usually stuck as the top answer on old questions, despite the fact that the situation has changed massively in the past decade and there are newer answers further down that give the new answer. Or better yet: when the top answer is a decade old and says "that doesn't even make sense, why would you want to do that, it's impossible, but you can look at literally the entire Handbook to see what you can do" (with a link to the frontpage of the FreeBSD Handbook) and you have to scroll down nearly to the bottom to find the one answer that actually answers the question (how to add an on-link route on FreeBSD) (and that it's not actually impossible like the arrogant jerk on top claimed)...
