What are the downsides to missing a legit listing on Craigslist versus falling for one of these scams? I think in this case, having a prediction function with high low false negative rate, but high false positive rate for scams is better than the inverse.
What are the downsides to missing a “looks to good to be true” listing that’s real? You miss the great listing... obviously. And great listings are not at all easy to come by in that area.
