My experience with Craigslist has been that there are a lot of keyword-stuffed scam listings in search results, but they are generally sorted below more useful results, and generally easy to spot and ignore. It makes sense to me as a strategy for leveraging fuzzy automation. Sorting is less risky than hiding or deleting. If the system gets it wrong, there is a still an opportunity for motivated users to dig down and find incorrectly down-sorted items.
