[Suggestion] Extra point option

All those price bugs recently (e.g. Deponia for 100 points), made me realize one thing: one positive effect of having an unusual steep price in points to enter a giveawy also means that less people, most likely only those genuinely interested will enter. So how about option to add some extra points when creating a giveaway? Maybe some flat 50 points you could select for your giveaways, that people would have to pay to enter. You'd not gain anything when selecting that option, but it might help to find those people who are most interested. That option could also be restricted to one out of 5 giveaways to prevent excessive use. What do you think?
