I took a look at some of the ACR patents I could find and it seems they typically use a perceptual hash time series to positively ID content, with short match rejection to avoid 'channel surfing' attributions. So the effective strategy would be a random feed of conflicting demographic content streamed for at least a few minutes each -- something like 5 minute shuffle of Miss Rachel, Game of Thrones, This Old House, 30 Rock, The Decalogue, Gunsmoke, CSPAN, Sesame Street, QVC, something like that. Problem is... who wants that actually streaming on their screen all day? My site as built probably doesn't actually poison the ACR data, it's more like waging memetic warfare/raising awareness.
