How long does a temporary ban last? It has already been 10 days.
In your sons case, it is likely to last two weeks, or four more days.
Then it ends in 4 more days. I think they go in increments of 24 hours, 1 week, 2 weeks, and a month. You’re almost done.
In the mean time, you can still earn credits through the custom challenges even while you’re credit banned. Easy way to still progress even if you’re banned.
Cheers!
