    Personally i would require original poster to tap "Analysis" button first.
    Once they do, button turns red and others can then jump on the train.
    If poster doesn't identify as "Analysis" button disabled. (Not difficult in software)
    Onus / honesty lobs with original poster and moderation / penalties easier to control.
    " Great " should be abandoned.
