I think they cannnot say, the ban was something like this: see every single console that get online with SuMo before release in their respective areas, if went before release date = ban.
It can be confirmed cause there peopl
A guy posted a few pages ago one to the Discord which contains this, but I think Nintendo will ban it and maybe ban other things in your 3DS.
IMO the best to do for ones with a single 3DS is wait the 15 days, and see if the 002-0102 online play ban is not lifted than buy a cheap 2DS for LFCS dump or a New 3DS.
The 022-2812 always was permaban, but can get bypassed if U care about eShop.
