Arduino SE would be a great place to test this out. We only get a dozen new questions in a 24 hour period, so if the users with only one reputation point go wild, it would do little damage (assuming the reader thinks it would cause damage).
Of course, the reputation points are like the points on the Tell-Lie-Vision show, "Whose Line Is It Anyway". Everything is made up, and the points don't matter.
I did a survey of my local grocery stores, gas stations, restaurants, etc., to see if any of them accept SE reputation points as payment. I have yet to find any business where I live that accepts them.
See Should Arduino SE participate in the '1-rep voting' test?
