I'm getting the sense you're very worried about being banned. The whole purpose of EmuNAND is to take that risk of getting banned while using hacks. For a foolproof way of enjoying hacks without being banned, you would do all of your hacking shenanigans on SysNAND because it will never be connected to the Internet whatsoever and you will play legally purchased games on the latest firmware using EmuNAND. This takes the both of best worlds except you must buy all games that you plan to play online with. Some people don't mind getting banned by Nintendo while others, including myself, will wholeheartedly take the risk while being as careful as possible to not give Nintendo a reason to ban us.
