Daily Dirt suggestion. start charging diamonds for duplicate ads.
as the title says. currently there is no means to stop or even slow people from placing as many duplicate ads as they have slots for. my proposal is that any duplicate ad (meaning for an already advertised item) regardless of price or quantity should start to cost something even if you wait the 5 minutes.
example first ad is free, first duplicate 1 diamond, second duplicate 2 diamonds, third duplicate 3 diamonds and so on.
I find it to be unfair that in order for me to use the paper I am constantly sifting through duplicate ads. this way at least I know its costing them something. this would be a win, win as I (and many others) wont see as many duplicates and supercell will make more profit.
I really don't care how anyone wants to play the game, its a game have fun. once it starts affecting me though I feel its unfair.
a superior product will sell it self, an inferior one needs lots of advertising.
