This can't be sustainable.

The few groups I'm in, local wildlife and pet bird groups, mainly consist of people asking questions that need to and are usually answered by posting links to local resources or regulations.

Since links within Meta are free, maybe they are hoping you will bring all the external resources into some Meta property?

That group will have it's own llama agent to read all those links and tell the members the exact answers to their question so they don't have to leave the safe zone of facebook and go off into the scary internet.

Perhaps share QR codes with links. :)

Yep, it will basically mean the death of Facebook. I don’t use it much, but the groups I’m in are for sharing local events (usually link to library page, map for meetup location, etc). Without links, those groups go away.
