It is not new. I gave you the link to the post when the policy changed.
This is May 2021
You can not use anything at all.
Do not do this.
You can’t use anything at all to help you. Nothing. It does not matter if it is “local” or if you downloaded it. It does not matter if you build a hardware rig to tap 5 keyboards at once on your desk.
You can not use any assistance at all.
No, it is not when it was added. It was added in 2021 and is in the post I linked. Anyone here on CS who has been dealing with questions about the policy is VERY aware of when it changed.
