From discussion elsewhere, there was agreement that if you routinely
   block spammers and junk favoriters the activity rapidly falls off.
   With the official twitter site and most clients, if you report abuse
   you also block the reported party. If the bot operator periodically
   checks whether it's blocked after favoriting or @mentioning, they would
   build up a list of who's best left alone. Their goals would include
   going unnoticed by Twitter governance. Anyone they can detect as
   blocking their accounts can be assumed to also be reporting the
   accounts.

     does this taper off? or just a constant stream of noise...
