I misspoke but if he asked my serial number, it's because the SecureInfo_A and an other file is the source of my ban. You understand?
Oh, I see.
Anyway, you should take care. This eShop thing that got you banned could be considered credit card fraud and is something that could even get you into jail (even if it's just an exploit to get eshop balance for free) as it's really simple to track from where you did it.
You should consider yourself lucky that you only got banned.
The way I understand, if it's really a permaban it shouldn't be reversible until we can fully decrypt the 3ds crypto and change your personal system identification. If they really want to issue a permban there are several ways to do it, sadly.
