that's what I wanna know too I injected hb launcher into Animal Crossing and ran NetPass so if you or anyone else finds me let me know as well :P
I'm thinking it will show cause the 3ds friend list shows the game name so don't see why streetpass mii plaza wouldn't as well
I'm gonna assume he thinks that was a screenshot of twitter when it's actually an embed and he saw "Follow" by the name in the embed thinking it was an image of your account 🤦
