Long story short:

1-Monetizing our mobile apps with Facebook Audience Network for more than 2 years without any problem.

2-Facebook reports via email a violation without giving us enough details to fix it.

3-Email doesn't have any way to appeal or request more info (really Facebook, we want to fix this and stay in your good graces)

4-Join a Facebook group for developer support ask a question and get out account frozen because they think it's fake and have to wait one week so I can verify I'm a real person ¿?

Seriously Facebook, stop treating us developers like sh*t
