Etsy 3, Artfire 1?

Some items look identical, even the background page that the photographs were taken on is the same. All 3 shops were started recently and have very sparse profiles/policy pages – doesn’t make sense that they would be owned by 1 person – why bother? I thought I found some unique earrings and now am wondering what is going on with these stores…

Meanwhile, I found a seller “Saffron” on Artfire, who has earrings from all three of the Etsy stores in her Artfire shop, with the same photos:

“Ripe Raspeberry Earrings” on Artfire (Saffron): http://www.artfire.com/modules.php?name=Shop&op=listing&product_id=1121432

“Peacock Mardi Gras Mask Earrings” on Artfire (Saffron): http://www.artfire.com/modules.php?name=Shop&op=listing&product_id=1120452
“Peacock Fairy Mardi Gras Mask Earrings” on Etsy (FairyThimble): http://www.etsy.com/view_listing.php?listing_id=38895031

“Emilia Earrings” on Artfire (Saffron): http://www.artfire.com/modules.php?name=Shop&op=listing&product_id=1120431
“Emilia Earrings – The Decameron” on Etsy (LindenGate): http://www.etsy.com/view_listing.php?listing_id=39223121

Why does one seller need 3 etsy shops to sell the same things they sell in a single shop on Artfire??
