Hey, Timelord! It appears that a temporary restriction was applied. It should only be a two week restriction in this case. There’s a variety of reasons and causes for temporary restrictions, you can see the list of temporary restrictions and our policy for it here:

We don’t have access for the exact reason for the restriction, but the most common causes are due to VPN usage or business connections.
