Monetize Facebook group ???

hi , i have a Facebook group active and i would like to monetize in this way. First of all my group is about sale and i would like to charge with a small fee per month some posts, Create a landing page with a paypal button and some instructions ....My question is if i get in trouble with law if i charge people for posts?Thank you

I don't think you'll get in trouble but that sounds like a pain in the backside to manage... rent your cover to one or more sellers on a monthly basis.

It is much easier than trying to get people to pay to post + it is much easier to manage.
