Multiple WhatsApp accounts got banned

[Dodger]

So I set up like six different WhatsApp accounts for my business to handle promo blasts and customer support more efficiently. The idea was customers could reach us on multiple numbers instead of waiting in line for one operator, plus we could send out deal announcements without spamming from a single account. Was working fine until this morning when I wake up and most of the numbers are just straight up banned. Can't log in, can't access the chats, nothing. What the hell happened here and how do I stop this from happening again when I get new numbers going?
