The prices for a ban award are too high. Sure, people have a ton of dramacoin right now because they've been earning it for months and until now it was just a status symbol, not a usable currency. While people's have thousands of coin right now, if they spend most of it now it will take weeks, maybe longer, to be able to buy another award. The prices right now seem to be based on current stockpiles, while they really should be based on how many popular posts it takes and how long it takes for people to save up for awards.
