So if I'm understanding, OP has a family account for himself and his never and nephew. He buys four copies of certain games, two for himself and one for the each of the children. He collects all the coins from these transactions, which if against Nintendo TOS for whatever reason.
Note: this is not atypical for reward programs. Most of these programs I have experience with do cap the points you can receive. Also, he collects coins from the purchases of other family members, which is also against the ToS but probably not that easily trackable. So far, this sucks but is not that far out there.
But then, it seems Nintendo is deleting the extra copies that the OP purchased? Or are they deleting software purchased with, in their eyes, illicitly gotten coins?
There we go. Yeah, that sucks but it is pretty logical. Again, it is important to note that many reward systems for many companies do have restrictions like this in place. Credit cards, movie theaters, etc.
Hopefully it works out for you.
This. Basically the only reason to start this thread is to use anti-Nintendo action, which should be bannable.
The fuck?
