Suup,
Got myself a fresh Switch, installed AutoRCM and ReiNX right after the purchase and went from 4.0.1 to 5.1.0 without burning Fuses using Choi.
Never been online with this console, what so ever (havent even inserted my WiFi credentials).
Just to clarify, if I use your DNS Settings (on 5.1.0) I'll mainly be safe to connect to WiFi and use it solely for the FTP Purpose (cause thats what I'd like to use) without getting banned?
(I'm aware, that I might not be safe on future Firmwares/6.0.0, but after a Firmware update I need to re-enter the WiFi Credentials again, anyway, before it connects to the Wifi, right?)
