Gnutella vs Spam (Score 1)

An idea popped into my head as I was reading about the possible methods of filtering spam from Gnutella responses. Instead of sending a random series of characters that the spam software could easily detect using a dictionary lookup, search for some real music that you are not trying to download. Then filter all sites that responded to that request. For example if you want some classical music request a song by a rock group and then filter out all responses from sites that responsed the the rock group request.
