They've scared off the most interesting segment of eBay with their policies that are actively hostile to smallest sellers, and their rubber stamp appeals processes. The most interesting segment were the individuals using it for garage sales or selling grandparent's old collection and bits of Victoriana. I could, and sometimes did, spend hundreds. There's almost none left. The very few that persevere have to walk the very fine line between unacceptable listing and opening themselves to the many possible scams. They killed that niche pretty effectively. I can't imagine using it to sell ever again.
Instead, there's medium scale businesses who can afford some percentage of fraud as "cost of doing business", eBay has become another OK outlet. It's an OK place for run of the mill, boring, ecommerce, especially at the cheapest end of the scale. There's now lots of businesses trying to tread those collectables niches with very overpriced listings or endless listings of old rubbish branded collectable.
Surprisingly, I find I am using eBay a lot more than I did five years ago. It's the place to buy batteries, cables and other trivia under £5 with some confidence there's no forgeries like I've had on Amazon.
As a saver I should perhaps be grateful, but their strategies seem to have been designed to turn me, and my peers, from thousand(s) a year customers to tens. If not intentional, surely they could and should have seen the trend years ago.
