Yes, sorry, I meant LAN play on the same actual physical location.

Why would they get banned if their Switch is clean ? Because they already played in LAN (so, without internet) with a friend who got a hacked Switch ? Did somebody already confirmed he got banned because of that ? Cuz I don't think it would
