Sorry to hear that. I've been looking throughout most websites and twitter to see if there's been a more exact cause. It seems like when updating pokebank, game freak forgot to fix some of the hack checks for both bank and online play for SuMo, therefore it's possible that legit events can be marked as "hacks". Not so sure how to alleviate the ban aside starting a new game so yeah. Agai sorry to hear this.
