Probably at most a few thousand people in North Dakota even know what emoviolence is, and probably a few hundred have actually been to an emoviolence show. Given that a large number of people seem to have posted on the Atlas only a few times and then disappeared, or were active in the past but no longer are, I'd have to say option 2.
I doubt a "few thousand" have, considering how many olds there and that 6000 would be 1% of the state, also the number isn't much higher than those that have been to an emoviolence show I'm sure.
