>Google isn't spying on your private files, but does scan them when you share them publicly. What's more likely: A) That they make a single-pass scan over a file for various purposes B) They make multiple, separate scans over a file at different times depending on sharing status and other factors I'd contend that it's more likely to be A, and that it almost certainly happens as soon as the data becomes visible to Google. I'd be very surprised if they didn't scan immediately to de-dupe and detect illegal pornography, for example. Once that's a given, it doesn't make much sense to do a separate kind of scanning later based on a different set of criteria; You scan once and flag for the respective detections immediately.
