The SHARE button will send the video out to everybody who views your page, and the only way they can see it is if they pass it along to everybody that views their pages.
Damn good thing I closed my account some years back …
Not that I advocate spreading this sort of thing but one can always change the privacy setting on the share screen to have it visible to “Only Me”.
So, do you not have a facebook account?
I would have to switch it to that right before “sharing” the video, then switch it back every single time because of some games I play and also because of 3 or 4 groups I am involved with that communicate mostly through Facebook.
Or maybe just not watch the video and get on with your life.
And you could do the same thing when it comes to viewing my posts. Win/Win for everybody!
That is quite onerous.
What happens when the last person on Facebook receives the video, and can’t share it with any friends who haven’t already seen it?
Hmm, maybe that’s their secret plan…
I ignore most of them as it is, but more and more videos are of that type nowadays, and they push the communications I want to see and read down to the bottom.
I’ve never seen this. I must have a higher class of friends. 
Believe me, if you required me to share your OP before I could read it - I’d definitely pass. As it is, your threads are always fairly entertaining but not usually for the reasons you intended.
It’s not my friends I think I’m having trouble with. it’s my “friends”-my compatriots in some online games I am currently involved in. I may just have to give them up eventually.
When I saw the thread title I thought maybe they were talking about my sister-in-law.
