User blog comment:Mckrongs/Don’t Hack Your Save File In Monster Hunter 4 – Capcom’s Watching/@comment-17735225-20131013144551

As a person who created a lot of custom quests for the past MH games, intending to create interesting scenarios for my friends to roleplay in or for challenges(But I didn't release on any sites). I hardly find altering the game's save normally can affect the hard copy of the game. But since the platform this game is in is pretty new and a 'virgin' for hackers, they might be something changed, either a trap to prevent hacks or some new registeration to the copy from the save that might cause permanent problems. Notably the streetpass thing.

I have nothing against people that hack just for fooling around, like owning everything with loads of bombs, revenge super rapid fire shots at all the monsters. But they could've just named their room like 'uberhackinglol' or just politely tell people that they're hacking, and to leave if they can't stand it. People that disagree with hacking also shouldn't bash the hackers as if they're scum breed of humankind. MH isn't a competitive game where you will constantly be at disadvantage/unplayable status if someone hack the game.
