In the end although their starting to care (there probably WILL be online bans) I don't think Nintendo cares.
Nah they definitely do, they wouldn't have changed so much of the old ticket system (good read from Scires: https://www.reddit.com/r/SwitchHacks/comments/759myu/the_eshop_and_cdn_explained_switch_edition/) nor added the unique public keys to make bans trackable and permanent.
