Your post or comment would still need to exceed the dust vote level. So a self vote, and a few purchased votes to get to the payout level.

Purchased or earned votes.

Yes very true. And a person could self vote and then look at day five and if no earned votes, then they could buy just enough to get the reward. (doing on day 6 would get some of the prickly picky people upset)

@Dustsweeper comes in handy for this as well.
