Now there's a business idea.. have an app running on your phone and PC that watches your "normal" facebook activity to establish a baseline, and ever so slightly perverts it over time using the same connection so the IP/location information still lines up. Slowly and methodically so the information doesn't get flagged as bogus. Start with overtly partisan political stuff since that's the easiest to classify.

Call it Social Chaff as a Service (SCaaS).
