A number of users report that when they are advised that their account is disabled, they cannot login to their Quest, and it can take weeks for Facebook to complete their review.
Surely it should be possible to still allow access during this time, but block certain functions like payments (if there's a concern re fraud) or multiplayer (if there's a concern re behaviour on the platform or breach of community standards).
Preventing access to a purchased device and previously purchased items on the store is a punishment that should be reserved for only the most serious of offences that has been physically reviewed by a human.
This would go a long way to restoring faith in the FB login requirement while balancing the desire of FB to ensure that social interaction is backed by an account in good standing.
I know this might require a change on the FB side, but as the most profitable arm of Facebook's non-ad based revenue stream, your voice should be important to argue for this change to the login function.
