The idea of a ReCaptcha for geospatial.. quite a few of us has certainly thought about it, and failed to come up with a workable asymmetric model. One was to use 4Square/object tags to train models to identify them in raster images and hence help auto label.. but the toolchain and scaling of this would be complex.
