Ok, I loaded my NAND backup, and now I'm back on stock, and I totally freaked out when I saw an error message appear when I opened friend list.
It was just a prompt telling me to update to use it, and when I did, it let me use it haha.
I have one 3DS, and it is not banned, I have Boot9strap on it, I have never cheated, I've had spotpass off since December, and I have no custom CIAs installed.
Still not banned, might not altogether. Since I've hacked it, I've only used FBI for 10 seconds and it didn't even log itself in the activity log. Am I still in danger?
