I haven't tried this myself on another account or anything, but I heard from a 主 that you can hold namahousou if you've got access to a community that lets users hold namahousou through it, even if you're not a Premium o 3o
That being said, it's kind of unspoken that you don't unless you're best buds with the 主 or something, so maybe this comment should be deleted after you read it =w=
