Violating Nintendo's terms and conditions can result in the deletion of games.

Nintendo has the ability to remotely access hardware and remove content that is in violation of its terms and conditions, a Nintendo gamer found out the hard way.
Earlier this year, a Club Nintendo promotion offered $30 in eShop credit if you purchased both Fire Emblem: Awakening and Shin Megami Tensei IV. After registering the games, users were provided with a code that could be entered in either the Wii U or 3DS eShop for the credit. The promotion ended August 31.
User “Honey,” who owns two separate 3DS systems, as well as two Club Nintendo accounts, had purchased two copies of Fire Emblem as well as one copy of Shin Megami Tensei IV. After securing another Club Nintendo code for Shin Megami Tensei from a friend, she registered the pair of games to each of her Club Nintendo accounts and received two $30 credit codes.
Instead of using one code on each of her 3DSes, Honey redeemed both codes on a single 3DS. She downloaded SteamWorld Dig and left the rest of the credit alone.
A few weeks later, Honey attempted to log into one of her Club Nintendo accounts and was greeted with a message that it had been deactivated. Her other account was deactivated as well. Honey checked the eShop on her 3DS and discovered that the remaining balance from the Fire Emblem promotion had been removed. Honey then went to check on her games.
“I left the eShop, started skimming through my games, and just as I highlighted SteamWorld Dig, it disappeared, right in front of my eyes,” she said.
The game, which had been downloaded to her SD card, was completely removed by Nintendo.
Honey called Nintendo of America and was told that she had violated the terms and conditions for the promotion, specifically stating that only one code could be used per account. Moreover, Honey had actually violated other Club Nintendo terms and conditions, including maintaining two separate accounts and registering a code for a game that the user didn’t purchase.
Honey was able to convince Nintendo of America to reactive her Club Nintendo accounts, but the eShop credit and SteamWorld Dig were forfeited.
“They didn't give me the [credit] back but I don't care, I was happy to get my accounts back. Also, I figured that if I push, I may not get anything at all.”
We reached out to Nintendo of America but received no comment.
