The problem arise because the couldn't contact their ex-staff so the facebook pages now become unmanaged and full of ads in their wall.
I googled and don't find the exact case like mine, i'm about to fill the "Copyright infringement" form, but i think it's not appropriate issue as well..
Can anyone give me clue which form should i fill ? What's the requirement ?
it's very hard to know the pages owner.. any idea on how to know the page owner/creator of a facebook pages ?
