So i was planning on purchasing a Sky 3DS+ soon and I was reading about how you should use a private header when playing online as to avoid getting banned. The main game I want to play is probably Pokemon Sun/Moon since most of my friends are getting it and want me to hop on too, going to buy it off ModChipsDirect (is there a better site to use in Canada?), as well as Mario Kart 7 and Smash 4. Anyways so I'm most likely going to get the Private Header off my friends Pokemon Sun cartridge. My question is, if we were to verse each other or trade or anything like that where we are both online together with the same header, would I get banned because based off what I know the reason everyone got banned in the first place is because everyone had the same header. Also bonus question I feel like I know the answer but just to double check, can i just keep using that Pokemon Sun header for all other games like Smash 4, Mario Kart, etc?
