I use Facebook exclusively to check for Corono related info in my community, because the local administration can't disperse them via normal channels. It's interesting, groups with 4000 people (roughly 10% of the local population!) will have anywhere from 3-30 likes on posts. The super hot threads have 50 comments, usually from the same 10-15 people.

I don't know whether the rest are silent lurkers like me, or whether they are bots, or FB is just inflating the numbers, but they surely aren't visibly active. I imagine it's not a special thing where I live, so you'll likely have the vast majority not posting publicly at all while a small minority is extremely loud. If the user count grows (hasn't the growth slowed?), most of it will not be seen by you while you look at posts and comments.
