I don't think a lot of you guys know how Miiverse works. You can friend or follow anybody. There's requests to video chat every few posts. Hell, I've gotten video chat requests so many times that I've blocked certain people. There's no penalty for going off topic. Anybody can talk about anything in any forum. People can and often do talk about competing consoles. Many even speak poorly about the Wii U or ask if they should buy the Wii U version of a game over the PS3 or 360. I've even witnessed a flame war on the Wii U to which I replied "A flame war on a Nintendo-only forum? If I didn't see it, I wouldn't believe it" There are pictures of boobs and penises that are just vague enough to not be boobs or penises. People use profane language but change it just enough to not be profane (or they use symbols). Every topic has several posts saying "Yeah! (the Nintendo equivalent of at Facebook Like) this post if you own a Wii U! Or "Yeah!" if you want me to buy this game or "Yeah!" all of my posts and I'll "Yeah!" all of yours!
I could go on and on. Nintendo Miiverse isn't the land of sunshine and happiness that a lot of people in this thread seem to think it is. It's a place where people troll, beg for attention, criticize each other, etc. I've made dozens of posts helping people set up NintendoTVii, asking people to spread the word on how awesome Miiverse is, giving out help in Arkham City, talking about how much fun my family is having in Nintendo Land, etc. I also have several posts that are just random (ie: My GF says I love you, Tim. I said, "I love youtube". She seems fine with that.) I've never asked for a single "Yeah!" but I've got like 600 or so. I'm not a saint and I'm not a monster. It's easy enough to find my Miiverse post history.
What got me banned was my random joke and my mention of my name on other devices (The actual User agreement says: "Personal Information: Personal information includes but is not limited to your e-mail address, home address, work or school name, and phone number. Never use Miiverse as a means of setting up real-world meet-ups." I've since learned that my Gamertag or PSN ID is included in the "Not limited to" portion of the code of conduct.) . Most of my replies are dictated by my audience. When they talk about consoles, I talk about consoles. When they talk about TV shows, so do I. When the subject is 80's music, that's what I'm talking about. I broke the rules. I still don't deny that.
