Would it be possible, maybe as an optional thing, to include a configurable upper limit to how many days you get the increasing amount of points for voting? For example, if you get 15 a day base, and it increases 5 each day you vote, after say 7 days, this becomes 6 days worth of extra points, putting you up at 45 on the 7th day, and resetting down to 15 on the 8th.
