> Facebook marketplace has been a boon for buy/sell to me and my family

Interesting. In my area, Facebook Marketplace is almost all stolen/burgled/shoplifted goods. People even call it "Fencebook."

Want a brand new, unopened PS/4 for $25? Fencebook to the rescue!

...huh. How do you tell stolen goods from legitimate ones? Obviously the price can't be the only factor since they could just try to sell it closer to a realistic price.

If you're buying something expensive, require an original invoice and check that the serial number matches. If someone is apprehensive about that, somehow they lost the invoice for the brand new unopened PS4 they bought last week, or similar, just drop it.

If they're selling close to the original price, just get it from a shop instead, that way you'll get warranty etc too (there's generally no warranty on goods with "lost" invoices).

In general, look out for suspicious behaviour. Are they willing to meet with you at their home or office? Do they readily share their phone number? Do they have many excuses (one of the most common tells for liers are an excess of over-thought out excuses) for not doing things transparently? If it's too good to be true, it probably isn't true.

Thanks! The trouble is all of these can fail for what I would consider legitimate reasons. Requiring a receipt fails if they just open it, maybe even use it a bit (or not), and wait a few months before selling it, since nowadays people seem to genuinely go through some stuff (e.g. phones) pretty quickly and not necessarily keep or have receipts, especially if they themselves bought it second-hand. Meeting at my home or office is not something I would ever feel comfortable doing, and is generally recommended against when purchasing online. Sharing phone numbers is something I'd only do when the decision to purchase has gone through and we're actively trying to meet up (obvious privacy concerns), etc.

It's not an exhaustive, binary checklist, they are signals to watch out for. They are basically surrogates for trust. If you're selling something that looks like it might have been stolen, you have to come up with a compelling reason to trust you. Meeting at your office and sharing a business card might be such a reason. If the only thing you're comfortable with is meeting in a deserted parking lot late at night, and only communicating over a throwaway anonymous email account, the counterpart is right to suspect something is fishy. On the other hand, if you have an original invoice from the Apple store, then it might be OK.

Sure, there are legitimate reasons for not getting any of these right, but if they get all of them wrong, be very careful.

It's not hard, once you know what to look for. Basic pawn shop training.

Erm... I wasn't asking if it's difficult, I was asking what do you look for? Why in the world would a set of things to look for be a subject to conceal?

Edit: never mind, just realized you're worried I or someone else is trying to sell stolen goods and will abuse such a list that way, sigh...

Because thrift store criminals spend _so_ much time reading deeply nested comment threads on hackernews...

maybe the response would take 20 minutes to write.

Then spend the 20 minutes, or don't. Writing "the answer to your question exists" isn't a meaningful contribution.

are you mad at me suggesting that they didn't write it down because they thought it would take them too long to write?

At any rate they didn't just say the information exists, they also said it was basic pawn shop training, so I googled "pawn shop detect stolen goods" the top answer was from quora https://www.quora.com/How-do-pawnbrokers-verify-that-the-ite... and there was something from a blog of somebody called the blog nerd which is a little difficult reading because of all the SEO keyword optimization he seems to have done

https://www.pawnnerd.com/how-do-pawn-shops-track-stolen-item...

there seemed to be a reasonable number of other informative links.

oops, the pawn nerd not the blog nerd.

In my area, Facebook is (and was even before the Marketplace) routinely used to sell clothes very cheaply - usually because the seller is buying wholesale and then selling it without paying taxes. You can get them even cheaper if the seller is a person from a rich family who doesn't care much for a profit, but uses this as their pastime.

Some of those are not stolen, they are just scams for users to send money someone for say an iphone X and then they get the item sent to them, which of course doesn't happen.

Where do you live?

I'm curious because I've used Craigslist all across the west coast in the USA and I've never found myself worried. I've used it for bigger ($XXXX) and small purchases ($X). Brand new and very used. Most people I've met are very friendly and decently honest. Flakey is usually my biggest complaint with Craigslist people.

Toronto, Canada. A somewhat major news item recently was that a guy was killed trying to sell his truck on Craigslist. These stories have popped on and off the news for a while now.

Other than that, the pseudo anonymity makes people uncomfortable with craigslist. At least, that’s the sentiment I’ve gotten from a few people who’ve used it. Contrasting that with the feedback I’ve heard about marketplace, people just feel safer when you can creep a buyer’s profile before they show up at your house.

Agree; this comes to mind: https://www.imdb.com/title/tt1486616/

Nextdoor’s new For Sale section is the best of these services imo since everyone is address-verified. I get a lot of spam from FB Marketplace but even with the spam, it’s miles better than Craigslist/OfferUp/etc.

Aren't the majority of rapes perpetrated by people the victim knew previously?

I don't think rape is the only thing people fear when meeting strangers. Unpleasant experiences or stalking creeps might be something to look out for.
