So far nobody has confirmed being unbanned after 15 days of their ban. Trust me, it would've been big news and widespread if a single unbanning ever happened. It's definitely permanent. The best solutions are to either have a secondary A9LH 3DS for online games, or have a secondary 3DS and use it's LFCSB on your main 3DS. Private LFCSB are absolutely safe. Search for a broken 3DS and use it for it's seed.So, just out of curiosity: Since it's been about two weeks since the initial Sun/Moon bans started popping up, has anyone who got banned back in those first few waves tried changing back to their old LFCS_B to see if they've been unbanned or not? I might try tomorrow night or Sunday since I was banned a little later on and it was my first offense, but it'd be nice to know whether I should even bother to try.
