Facebook employees will ignore your calls for help, and there is no proper way to contact them regarding a disappeared account.
You have to pretend to be an active Facebook user in order to access services tailored to developers, such as Wit.ai.
Imagine having to like YouTube videos and subscribe to channels, maybe post a comment sometimes in order to not wake up with your Google Cloud instances gone without notice.
That's how Facebook developer services operate.
