A lot of it is driven by Chinese middlemen and get-rich-quick schemes that are more than happy to burn the marketplace to the ground if they can make a buck in the process.
The challenge is that in the beginning the revenue is good and it's hard to say no to revenue when you need to beat the street every quarter. It seems so manageable at first. But unless you've lived its very hard to wrap your head around that you've planted the seeds of your own destruction.
Add velocity controls for the IP address and you'll get a thousand sign ups from a thousand IPs. Limit it by device and you'll see a thousand devices. Flag the images using a perceptual hash and the images will come back superimposed on random pictures of food.
At some point you find that your accounts are now traded as a commodity on underground markets at various prices by teams that specialize in creating accounts, aging them and selling them for x cents. Add enough restrictions to new accounts and you'll find existing shops being taken over and flooded with listings.
And do all of this while still having an "effortless" signup experience for new legitimate vendors.
Routinely (i.e. daily) I see activity that may involve 500+ unique IPs and 2000-4000 attempts. The type of activity that I see isn't close to what would be considered an extreme-worst case scenario in the industry.
Assuming the right economic incentives these groups are over time able to duplicate about any behavior that would be seen by a typical customer. For example, they can effectively remote desktop into a device and create a sleeper account and then come back to the exact same device a week later once the probation period has expired and execute a larger attack.
Also it is hard to fully understand that markets where labor isn't scarce fundamentally organize themselves differently. For example one recent attack that I'd see involved multiple attempts from multiple IP addresses and multiple devices all within seconds of each other and using the same credit card for registration. For a while I marveled at the technical skills that would be required to orchestrate such an attack until I realized that it likely was likely a dozen people in a room sharing the same credit card number and launching the attack in a coordinated fashion. Low tech, but extremely effective when labor is cheap.

Something along these lines must exist where legitimate sellers can live with it while the cost to the spammers must be unacceptable.
nobody would spend $1000 on what is essentially a gamble (since etsy is determining whether you're 'selling mass produced junk').
sellers already feel like etsy is way too buyer-friendly (at the expense of sellers).
It's not easy but you have to invest in maintaining the credibility of your platform. Machine learning helps but these problems have existed pre machine learning and can have more traditional economic solutions.
EDIT: The deposit could also depend on your prices and sale volume. This way really small players can pay in with a lower deposit. There are probably many variations but again the key is to make it a losing proposition for the spammers/dollar store guys assuming you want them off your platform. If you're only doing machine learning/filtering the cost to attack the system and try to get in is too low.
Hand made does not scale.
Besides, when the point of the site was unique handcrafted items, selling manufactured stuff undercuts the one thing that makes you different from your competitors.
I can't understand the argument you're trying to make. It's like saying that fine art doesn't scale because painters are so slow, so art galleries should postcards instead. Perhaps that would indeed be more profitable, but then you're not an art gallery any more, are you?
However they've sold a classic Silicon Valley "high growth" story to investors that they're now beholden to as a publicly traded company. That growth story can't be delivered on grandma's handicrafts.
Hence the site being slowly transformed into yet another generic online marketplace for drop-shipped junk.
It's ultimately a giant recipe for failure. The company DNA and core brand are at odds with the investor expectations around tech companies.
Less so than most - they're a B corp (is that the term?) with higher priorities than shareholder value.
It most certainly can if you have the proper equipment. You can facet two or three stones by hand on flat grinding surfaces, or you can get a rotary lap wheel and spend a day making ten stones, then you can get a mechanical precision arm for the rotary lap and now you can pump out 20-25 high-quality stones per day that sell for good money.
It all depends upon your tooling and experience.
From the articles I've read they've done this to increase the number of sales (cheaper items = more conversions) but I think it's been slowly costing them their customer base.
Hopefully they realize this and start banning mass produced items and listening to their artisan stores feedback again.
