No, because I looked at the editor notes and no submissions for that site were ever deleted. It is possible I imagine that you got snagged by the spam filter last time and it is sitting in a manual category waiting to be moved. That is the only way it could still be pending. Otherwise, it is just due to the errors we have been encountering. Pretty soon the upgrade will be done and things will be easier.
I will also mention that when I deleted the duplicates I made a note that it wasn't spam and that the large number of submissions were due to a submitting error. I definately left one, also, so no need for concern. <img src="/images/icons/grin.gif" alt="" />
