So I downgraded to 11.6.0.39E after I heard the latest updates apparently ported the Switch's piracy detection methods over to the 3ds. Does anyone know of an update blocker or DNS server that is confirmed working right now?

But everything is risky now. Especially playing games you haven’t purchased or downloading updates for games you don’t own.Primary DNS: 168.235.092.108

You can safely update to 11.9. The anti-piracy measures just prevent you from downloading games for free off Nintendo's CDN. That's why freeshop died. Staying on 11.6 won't really solve anything.
No they didn't do this. There were changes on the CDN that require a ticket to be sent to download a title. This makes 11.8+ a hard requirement to use the eShop now.after I heard the latest updates apparently ported the Switch's piracy detection methods over to the 3ds
