Sites that took a hit were not PENALIZED, and that's important to appreciate: not a penalty! There is no message in their Webmaster Tools about any problem.
Thank you. Maybe penalty vs filter vs whatever needs to be reiterated more frequently.
Yes I know it *feels* like a penalty, but I really think it's more a 'reclassification'
