That's not even an issue for them now with checking unique IDs. They're just outright banning entire switch 2 consoles that use duplicate unique cartridge IDs which appear after dumping the game data onto a Migswitch cart. They see the same ID in two places at once? That ID is poisoned now. Any time that ID comes online, it bans a console. The fact that they're doing this and still remaining profitable is a testament to customers blind love for this company's products.

It has also killed the second hand game market for me regarding switch and switch 2 games.
