This is a poster with a relatively small number of followers and the post only has a $30 payout. We're it ever at a place of less than 1 view per $ payout I think it's completely fine. The money drives viewers and for smaller bloggers it's the only way they can get noticed.
The "boosted" payout is still with in the realm of normal. There are many many posters with large followerships receiving much much more for much much less.
