It happens quite often that low-quality questions receive spam answers. Just a few hours ago, I came across one such question (now 10k+ only).
The above post received a spam answer from a user with just one reputation point. Why isn't there any mechanism to stop such users from posting answers on SO?
I know we can flag specific individual answers, but why should those answers be shown in the first place? Can't we do something similar to what we do with suggested edits? Answers from users with minimal reputation could be placed in a queue for moderation before being displayed.
Would there be any consequences to this approach? What do you think?
