I've been seeing it too, for sure.
I've been picking off the bad ones for years and enjoying the benefits.
I always wondered if there was any data proving or disproving that pre-emptive negative keywords (those not found in detailed search query reports) also had a positive impact.
I'm trying to get some insight about the rifle-shot type of management where you are picking off negatives that you know vs the blindly eliminating tons of words that you don't see in query reports.
