I feel I've bumped into the same frustration I've seen from many other developers on this list with this request. Specifically I feel this will fall between the cracks because there is no community list of planned and denied suggestions for future improvements such as a bug/request tracker. And I am taken aback at the immediate jump to a concern about whether I send SPAM or not.
Chris, here's a link to a definition of acting by proxy:
http://www.answerbag.com/q_view/441476To sum up the definitions posted there and to clarify to you my use of the term Proxy I was referring to the ability of sending email from an API user through an OAuthed user to another user. I offer this definition because I cannot follow the logic jump in my own head of Proxy > TOS violator.
I LOVE Etsy's community centric approach but I don't feel the LOVE from the API yet. Maybe I'm just too much of a noobe and should settle in to more conversations here before making the same suggestions others have made before me, if I can avoid that.
