oh young grasshopper, I see you dont know that money launderers love the ebay hype cycle. Its REALLY common on high dollar hot items to have phantom transactions where parties are on both sides of the transaction to clean illicit money. The high price tag and high volume amount of transactions hides the illicit signal. I have tried to buy a few of these mac studios only to have the transaction cancelled because I wasnt the dirty money on the other side.
I said there are lots of scam listings. And then discussed a second issue which is fake listings that are designed to launder money. There are both. Some of the fake listings are obvious: way under priced, listings for “original boxes” not the actual computer. So that’s why I don’t want to buy off of eBay for this category. But I did also buy what appeared to be a reasonable listing and it was canceled. I can’t prove why but two sided money laundering is a known thing
