A Nintendo Switch 2 user got banned after downloading patches for preowned game cards bought off Facebook Marketplace, due to Nintendo's anti-piracy measures.
Nintendo attaches unique codes to game cartridges to prevent piracy, leading to bans if the unique code is detected online more than once.
The user was briefly banned but unbanned after proving the legitimate purchase of the game cards.
Nintendo's strict anti-piracy policies have been in place for a while and have gained attention with the release of Switch 2 and recent amendments to user agreements.
