Does anyone know of actual pool that allows this duplicate share submission?
i dont thing that there is stupid enought pools that allow you to do that, why will they allow you to do that? they will loose money if they do that man...
edited: just to quote this, was a better reply than mine
There is no public disclosure here. You are talking about client software aren't you? No pool software is stupid enough to allow you to submit duplicates and get paid for them and there is plenty of free and open pool software code (mine included) to see. The pools will just rightly reject duplicates.
