[Scspamcop] comments to abuse addresses

[RandallW]

When I use the parser there are boxes at the bottom of the screen allowing 
comments to each potential abuse address.  Lately i've been plugging the 
spam-originating IP into the Spamhaus lookup box and the Cbl.abuseat site; 
if there's an entry at one or both of the sites I make mention of it/them in 
the Spamcop parser comments boxes.  Do the ISPs actually read these 
comments?  Am I wasting my time?
