Avoiding facebook bans

If i have own a closed group on facebook with a few hundred thousand members how can i exploit it?

I've never advertised on facebook before but ive heard they're pretty ruthless with banning advertisers. I read about iFrames here but i dont have a serperate website to host the page on, so are there any other ways to make money without losing the account? id rather not lose this group.

please i need help on this, expatiate more on it. thanks

You can status updates on group related to your niche for few hours that can give you some cash.
you can promote cpa offers related to niche but for that you need to have a landing page .
you can promote amazon offers if you feel your audience would make a purchase.

I think i figured out a way to do it. I think i will just create multiple accounts and create pages on them, then advertise the pages on the group. They cant ban you for linking to other facebook pages right??? then on those pages i can just link to something like mylikes or maybe amazon affiliates.
