OJFord is presumably implying that at least one person exists who gets their attention, so not EVERYONE does that, and furthermore that OJFord is people, so doing that is to some unspecified extent actually counterproductive to getting attention from people. The entirely absurd premise you suggest is in no wise necessary for making sense of their comment, since there exist far more plausible implied premises.
