Painful histories

So it appears that members of the church continue to submit names for temple work that they’re not supposed to, particularly lists of victims of the Shoah. (Evidence for this: The first presidency sent out a letter to be read to the members of the church. Again.) This leads me to two questions:

1. Will the members of the church ever learn?
2. Are members of the church allowed to submit names of victims of the Shoah for temple work if those people are their direct ancestors?
