“We have determined that library or SDK (com.mobfox, com.mobfox.adapter) your application being used in violation of the “Developer Program Policies.” Please note that, according to the “Developer Program Policies” requirement, since August 1, 2014, when the update application or upload new applications, all must comply with the “Developer Program Policies,” the ad ID (“advertising ID” ) terms.

Change their sdk in your apps. But MobFox adapter is not repaired since the first half of February. So I have deleted their library from my app till they will correct the adapter for mediation.
Maybe it is too old and uses the old non-changeable advertizing ID instead of the new user-resetable advertizing id. I think that this is only required for apps updated since August
