An email really wouldn't make the response any faster than normal. It's kind of a "Boy who cried wolf" sort of deal, if the majority of reports are pointless one would be less inclined to read through all of them just to find the one or two that are actually useful. There's really isn't a whole lot, if anything, that can happen that would really make that potential one or two second quicker response necessary anyway.
