The recent wave of Nintendo Switch 2 bans is generating a remarkable concern among the gaming communityThe main reason is not always obvious and, in many cases, it affects users who have apparently followed all the rules, especially those who purchase second-hand gamesThis situation is putting the security of the used game market itself and the experience of owners of Nintendo's new console into question.
Since the launch of the Switch 2, Nintendo has toughened its anti-piracy policy., implementing automatic systems capable of detecting any hardware modification, use of MIG cartridges or physical games that have previously gone through unauthorized copying methods. Although the measure seeks to protect the integrity of its platform, the System errors have led to user blockages who simply chose to save on the purchase of their games.
The usual case: bans after using second-hand games

One of the most talked about examples is that of a user who inserted several second-hand physical games on your Switch 2 to update your library. Without warning, and after installing the corresponding updates, the console was blocked with the well-known error code 2124-4508This type of ban is especially restrictive: It affects the console and not the account.so that Changing users or using another account is of no use., leaving only the option of offline play.

This puts those who purchase used titles without knowing their full history in a difficult position, as they may inherit problems from a previous owner.
How Nintendo has responded to affected users

This zero tolerance policy puts the traditional market in check second-hand games, a widespread practice among console owners. Buying a second-hand physical title—even if it was legally acquired— may carry the risk of receiving a bricked console whether that game has been previously cloned or modified, something that consumers can hardly verify before purchase.
