The site would also collect identifying information about everyone who transacts while using it. Maybe phone number, or driver license photo. You are not allowed to have more than one account, although you can have multiple "personas" if you wish, each with their own ratings. (but creating multiple personas cannot fool site anti-abuse staff, who can all obviously see the same account behind it) Creating an account is hard. The site would employ advanced protections against account takeover.
Whenever you buy and sell from someone, perhaps you can see the "7 degrees of Kevin Bacon" style interpersonal connections that link you to them via vouches. If fraud happens, it makes all of your connections look bad, and there would be an incentive for them to shun you, if they care about retaining their access to the site. When fraudsters get onto the platform, you can always trace their vouches back to the "bad apple" who showed poor judgment and began inviting the wrong certain people. Indeed, perhaps in order to retain access to the platform overtime, you have to keep getting vouches every once in a while.
Big sites would not use these policies since they would invoice friction on purchases in result in lower conversion. But perhaps there is a niche somewhere for a highly trusted online auction house.
I wonder how far a system like this could go in stamping out fraud online. It seems like the problem with fraudsters is that they can always keep coming back with new accounts that everyone is forced to treat with the certain default degree of trust, and then the fraudsters exploit that. If you made it difficult for each person in the world to have more than one account on the service, then anyone engaging in repeat fraud would very quickly stand out as such. (As many personas as you want, but only one account)
Or phrased another way, its like the gun control problem where the only people following the gun control laws are the non-criminals you have no need to fear, and the people who don't play by the rules are the only source of problems.
Seriously boggles the mind what people are willing to say on Nextdoor.
Unfortunately even though eBay violated their own written policy by siding with him, this is SOP for them. They have a decades-long unwritten policy of shitting all over their sellers. This became apparent when they removed sellers' ability to leave negative or neutral feedback for buyers, which led to a huge influx of scammy buyers. eBay didn't care because more buyers means more revenue, and the sellers who had built their entire business on eBay had little choice but to stick around for the shafting.
1. Craigslist is slow. On eBay, you're done in 7 days. It can be pretty hard to get full market value on Craigslist in anywhere near that amount of time, if at all, especially if you're in a smaller city.
2. People on Craigslist are flaky. I have no idea what compels someone to email a seller with interest, schedule a time to view an item, and then just not show up, but they do it all the time. Why even bother?
3. People on Craigslist are needy. On eBay, I list and then I sell. I am selling two items on Craigslist right now. You should see my phone's messaging app. It's full of the unknown numbers of un-serious buyers asking pointless questions they'll never follow up on.
4. People on Craigslist are, well, people. That means I have to meet them somewhere. Arranging that always ends up being more difficult than a trip to the post office.
I view the tradeoff like this:
eBay = simple, easy, fast, but with a nonzero likelihood of total loss
Craigslist = nearly guaranteed to be difficult, slow, and annoying, but with a very low chance of total loss
I don't think it's an easy decision. They are definitely not interchangeable.
I was moving and had to sell a lot of stuff fast. I scheduled around 6 people to come look at a futon. 0 showed. Even after I offered to give it away for free. Huge waste of time.

I was beginning to think that buyers on Craigslist are instructed to act this way. :P
Real pity because it's hard to know where to sell that sort of thing these days.
