Ahhhh I wasn't understanding. So it was clearing them that got him banned.The user in question as well as the rest of us send a lot of data to Nintendo. One of these things are error logs. You know, those error codes you see from time to time? If you've never encountered an error code, then your error log is probably empty. However, if you connect online, these error logs are sent to Nintendo. What happened to this particular user is that when he connected online, his Switch had no error logs despite having sent error logs previously meaning he hacked the console to clear them which resulted in a ban.
(Because I was arguing over the fact that crash log/error log aren't a ban flag if none are sent)
