Some Switch 2 users have reportedly been banned by Nintendo after trying to play pirated games using special cartridges. Back in May, a month before the Switch 2 was officially released, Nintendo updated its Account User Agreement and Privacy Policy to include a new clause that explicitly prohibited users from "bypassing, modifying, decrypting, damaging or tampering" with Nintendo's games and services.

Nintendo also added that it has the right to "render your console unusable" if the system detects that a user has violated these rules. At the time, many netizens questioned the severity of this policy, but now it seems that Switch 2 users who use popular MiG Flash cartridges have indeed begun to be banned and can no longer connect to Nintendo's online services.
Under relevant posts, many netizens left messages saying that they had similar experiences. They said they only used MiG Flash to play backups of games they had purchased legally, but were banned shortly after using it.
One user commented: "I used MiG Flash after the update came out, and the console was blocked. I logged in to my account using the OLED version of Switch and found that the account was not blocked, which means it was just the console that was banned."

Another person also said: "I was banned just now. I only used my own backup games on MiG, and I was still banned. At least now I can confirm that they can recognize the use of MiG Flash."
In a thread on the Switch2Hacks forum, a user issued a warning for others to refrain from using MiG Flash on the Switch 2 for the time being. He wrote: "Remind everyone not to use MiG Flash online on Switch 2 for the time being. My Switch 2 was blocked just now, and the account is still fine. I only use my own game backup, but maybe Nintendo has new recognition technology for MiG. I am still using it online. It's so stupid. I blame myself."
