Experienced customers can spot most of the scams easily. A small trader who has good feedback for selling a couple of lawn chairs a week suddenly has a vast portfolio of 4k TVs, top of the range dSLRs and high-end laptops, all at half price. A naive customer doesn't look beyond the overall feedback score, or see anything odd in the line in the description that asks them to contact the seller before purchasing, or in the official looking email they get back that links to an 'Amazon' purchase page that helpfully relieves them of their cash. But Amazon isn't naive, and has vast resources they could be using to clamp down on this sort of scam. Why not have an easy way of reporting obviously hacked accounts, rather having to dig through their help system looking for something vaguely appropriate? Why not keep a close watch on the lowest prices of popular items that are repeatedly used as bait? I used to see pretty regular price alerts on a camera lens in my saved item list that invariably turned out to be scams. Why not search item descriptions for email addresses (or obvious address obfuscations) inviting purchasers to contact the seller outside Amazon? Scammers often re-use the same text, and even the same email addresses, for the next hacked account. Why doesn't anyone check when a long-standing seller's established shopfront changes drastically overnight? Basic analytics ought to ring alarm bells here.
