Dude, unfortunately you've killed all the knowledge sharing here. The others don't want to share info here anymore because they're worried you (or others) will misuse it.

With a system as secure as Whatsapp (LOL?) announcing things are no longer a good idea.

As for getting Whatsapp to fix something, you notify them, give them a deadline, then release (fixed or not).
POC is also not a bad idea.

Releasing it isn't a great idea. I don't want MY Whatsapp account abused.
