Didn't say anything about piracy. You seem like the type of person who would complain that using the Mew glitch in Pokémon Red/Blue/Yellow is cheating and get on people's cases for using it.Everything is about cloning and piracy, isn't it?
What I don't like is when there's a programming glitch in the game that lets you get free items (it's harmless, really, it's not like a game-breaking issue like Pokémon X/Y had when saving in Lumiose City - THAT was a valid reason to force an update) and it gets patched just to ruin people's fun.
If you want to cheat, by all means cheat. Especially with a game like Animal Crossing which is primarily a single-player game, you're literally not harming anyone else in the slightest by using an item cloning glitch. And all making an update did was enable people to charge real money for cloning services. >_>
