You get 10m ban on 1st? log in on 2nd. Banned on 2nd and not yet unbanned on 1st? Use 3rd… 4th, 5th… whatever You need, it’s a free game now, use that.
You won’t have access to Your skins, or BP progress, so it might be an issue if You care about it, but other than that - You can play perfectly well.
