MoPub removed all kid-oriented inventory without previous notation, so I can’t see any history information.
Nice step, a?
They warn about 2 month ago: http://forums.makingmoneywithandroid.com/advertising-networks/11270-mopub-will-suspend-child-targeted-app.html.
They have remove three game of mine too. But now ads still running, just disappear from Inventory, i don’t know when they will remove it from their server 
but why ? I can’t think of a reason…
They don’t want to deal with COPPA probably? Although they should only block MoPub Marketplace in such apps. Mediation platforms that remove apps are not good mediation platforms. One of the reasons of using mediation is to make sure your apps won’t be without ads because of some network deciding to ditch you…
They warned about traffic stop, but not about removing inventory and as the result all related information.
only Marketplace is affected? Meditation between others networks is still working for you?
how can they control this? just because a checkbox???
They do, this is their other email, check your spam folder:
