Quick question about Facebook sharing

[SparklingTwilight]

If I share a video of my DC to a custom list of friends, are the friends then able to share it to anyone or is it only viewable by the people who I allowed to see it?

Depends what your settings are. You can share to friends or friends of friends.
IMO nothing is safe on Facebook. Doesn’t stop me posting though 😬

I shared it to certain friends.
If I play it, there's a big arrow saying "share" but I don't know if that's because it's my video.
Technically DH took the video but I edited it because he didn't want it taking up his disk space. Maybe I should take it down!
