This has been my experience as well. Etsy in just a few years has gone from a artisan marketplace to a bunch of mass produced junk. 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…
I wonder if they can police the reselling of mass produced junk. I'm imagining initial efforts, making a notable dent in the problem, and then kicking off a "Made By Me" social media campaign. If resellers stopped seeing Etsy as a easy way to sell dollar store items at artisan prices, made that'd curb the problem a bit more.
Something along these lines must exist where legitimate sellers can live with it while the cost to the spammers must be unacceptable.
