Can you explain why to start such a group on Facebook? Why does the various interesting information need to be dispersed even more? There is FAC, there is Victor's forum with not-so-strict rules against eBay or other sellers. For me, social media (such as Facebook Twitter, Instagram etc.) are neither suitable for discussion, nor are they a good data resource, because searching them is a tragedy. The classic discussion forum wasn't invented for no reason. And it works pretty good! So?
