And in the event that you don't search, the simple answer is that it bottle necks duplicators.
All you realistically have to do is simply copy your game save to your thumb driver, paste it on another profile and then send your unlimited amount of paints to your other account so you can have multiples. Trading restrictions prevent this.
I'm asking because, I can send 5 cards a day, but get 10 every day. So in that respect, I will max out my items without having an opportunity to get rid of it. This is what I don't understand.
Well....my problem still exists then. If they won't allow us to delete cards, or send more than 5, they shouldn't have a limit on how many we can have.
