Nintendo is blocking pirated games for the Switch console from accessing the Nintendo network.
Looks like we've got confirmation that Nintendo is banning gamecart certificates (I guess people aren't taking my advice...). The relevant error for trying to use a gamecard with a banned cert is 0x1F727C -- 2124-4025.
According to posts on the SwitchHacks subreddit, Nintendo has already begun banning game cart certificates. Server-side checks can determine whether a copy of a game being run is legitimate, be it a game cart or a digital copy. It will provide an authorization token once authenticity has been established.
If the server-side checks determine that the software being run is an unauthorized copy, it will block the game from connecting to online play and Nintendo can also easily ban a console from accessing its online network entirely.
Pirated games can be run on Nintendo's Switch console because hackers discovered a flaw that could be exploited to run arbitrary code.
