If you are a bit of a potty mouth, you probably noticed long ago that swearing of any kind on the 3DS is prohibited. This is a smart move by Nintendo, as keeping the handheld free from profanity will obviously please parents who are concerned about their children being exposed to naughty words, or worse still being the recipient of cyber-bullying on the 3DS. These restrictions apply to StreetPass Plaza, Friend Messages and of course Miiverse.
However the list of blocked words can be a bit overzealous at times, leading to seemingly harmless words being banned. Of course words have different meanings in different cultures, something the predominately UK-based writers of Nintendo Life have come to realise over the years when writing for an international readership.
Recently some Reddit uses have been tinkering around with the 3DS' firmware and have discovered the "bad word list" which is obviously very NSFW. Of course we couldn't resist having a look, if only to find words like "smeg" are banned, which seems fairly harmless to us. After all, Kryten from Red Dwarf would never swear would he?
It's very likely that a similar list of restricted words will be baked into Miitomo, so watch out!
If you're wondering who the heck Kryten is, then you need to watch Red Dwarf as soon as possible. A good starting point is below, where Kryten is still 'practicing' his insults...
