Did you have any luck or are you still in the same position?
I also have dealing with the same issues except they removed 2 of my apps that were already in the App Store without warning for the same issue you've experinced.
"Guideline 3.2.2 - Business - Other Business Model Issues - Unacceptable The primary purpose of your app is to encourage users to watch ads or perform marketing-oriented tasks, which is not appropriate for the App Store."
It's been over 45 days and multiple rejections all without any additonal explaintion from Apple. Did any of you find a solution to this issue?
