            If this is what you mean, then it is impossible to do so automatically.
    This definition requires determining the motiviation for the registration,
    which cannot be done by any technical means. For example, this definition
    would exclude a domain temporarily parked for a few months while a service
    is prepared and tested.

            If you mean determiming if a domain is likely to be parked or definitely
    has some other set of characteristics, it helps to work that out in precise
    detail. I'm not trying to be a pain, I'm genuinely trying to be helpful.

            For example, a commonly asked question is "how can I tell how much memory
    my program is using" and the canonical answer is "define what you mean by
    'using memory' and the answer will be obvious (or at least you'll be on your
    way to getting it). (Physical memory? Virtual memory? Is the memory
    footprint of a shared library to be counted as 'used'? What if this is the
    only program that's using it? And so on.)
