Cool. Thanks for the feedback and follow up. I suspect one search running every hour or so may not be enough to trigger it but if multiple auto searches are happening on multiple devices in the same household (as in the case of who I was researching this for) it probably will auto block for the 24 hours or so.
So this actually doesn't seem to be as bad as I thought. Maybe the 3rd party apps should set defaults to run less frequent and to also give a note about too many searches running at the same time may cause issues. A little education goes a long ways sometimes.
