I do believe that listing the same items on other venues is a breech of Etsy's terms. Because if you sell it off the other site, then delete it here, it will be seen as trying to skip payment to Etsy.
This is not true. If you only have one item, the worry would be selling it to two people at the same time. If you have more than one... Go fer it!!
