Does factory resetting your device clear the error logs? I imagine so, so what does Nintendo do in those cases? If you go online and have a few legit error logs, then your internet gets turned off (or whatever) and can't connect, then you factory reset, it seems like that would look like the same thing to Nintendo. Unless clearing error logs deletes a file on the FS, in which case you'd just want to make sure you generate a fake legit one (enter incorrect wifi information and try to connect to wifi, etc.) before going back online.
