This is very true. The economics of spam have changed radically over
the past few years.
At one point, the keyservers could be considered "uninteresting" to
the average spammer: lots of invalid addresses mixed in with the good
addresses, the annoyance factor of pulling addresses from a keyserver
that only returns a small fraction of the entire keyring per search,
etc. Nowadays, many spammers aren't using their own bandwidth or CPU.
So why *not* hit the keyservers? It costs them essentially nothing.

This was my conclusion as well.
