BUT -- I will say this. Depending on the product it's pretty self-evident who the individual makers are on Etsy. If you do your research, like doing image searches, it's also usually pretty self-evident what is mass-produced and/or counterfeit.
So I still use Etsy, but only in a very limited way, and only if I can assure myself with some level of certainty that the item I want is actually what some individual maker produced themselves.
Nothing wrong with mass-produced items if they're not counterfeit, I just prefer not to get them through Etsy.
