And I want to know how they figured out we had a Barracuda.
        
It's not that hard, much of the time -- they tend to make
themselves visible via their poor behavior.
      
Is there some very specific poor behavior you're referring to?
    

I don't know what Rich referred to, but Barracudas used to be easy to
spot by backscatter levels:

Yes that was what Rich was referring to, however, that I suspect is not
what Spamhaus are doing.
