Hi 2 pt,
That is a very interesting question, and although I am thinking no - I did ask someone over in our bank to verify this. I will post here soon as soon as I hear back! :-)
It is not run by USAA. Etsy is an online marketplace for people to sell their handcrafted, salvaged, or repurposed items. (somewhat similar to Ebay, except with a more handcrafted-friendly environment)
You most likely "wandered" into Etsy because there was a series of articles in the member community discussing Etsy Entrepreneurship. [five-day series spotlighting military spouses and service members who are using Etsy to channel their creativity, build careers and overcome obstacles created by frequent moves.]
It's a glimpse into the lives of USAA members who choose to participate in Etsy.
My mother would use this as an excellent teaching example about not clicking on hyperlinks without checking the website you will be redirected.
If you are disappointed with the products that Etsy's independent sellers display for purchase, then you might enjoy sending Etsy a recommendation that they segment their online marketplace -- a kid-friendly version or an opt-out button for accountholders to reduce or remove displaying for-sale articles that are of a nature you deem offensive. [although they would both take some significant programming/implementation and would likely take more than a year to put into place, so I suggest not expecting a month-long turnaround by Etsy]
