Hard to tell, one of the early coders, sneak, I think, said he didn't care about the 1st million accounts, he was worried about the second.
The timing of such a statement led me to believe that several 100k accounts were being created to pad the numbers of new users adopting the platform.
It's hard for me to put anything past a coder looking to get paid for easy work.
Or, anybody really.

Until there is enough inflation to dilute the stake enough to end this issue, attacking is futile, imo.
We would do best to teach the newbs not to vote on posts with more than 5htu on them.
Doing this will sooner spread the rewards to those without much.
If we tell them to power up 1mv's worth, soon there won't be enough to go around, and the price should rise.
