Anyway, I thought it'd be great if there was some sort of filter. Assuming all new photos are scanned for their content anyways, it would be easy if that respective person could just set another tick to mark a photo as explicit close-up. We could then in our settings select if we want to exclude such photos globally. Alternatively, they could implement a 'rating' system where we could mark pictures as 'do not show again' and would not be bothered again.
Just a thought.
