@tedster, so surely it can be made more sophisticated?
Certainly - and in fact we do that ourselves so I'm sure Google does, too. I was just trying to communicate something about how essentially simple the first ring of detection can be (if you have access to good sentiment analysis, at least.) There are many other spam footprints for social data, too.
