About 10 days ago, my 3 year old son developed Bell's palsy in a period of 24 hours. This means the right side of his face became paralyzed, for no good/known reason. Most cases of Bell's palsy, esp. with toddlers, go away within about a month.

I'm taking videos of his face every day to track progress, to see whether it's recovering. Also, I'm sharing some of the videos on a Messenger chat with other concerned family members. Obviously, since this is his face, I'm not in danger of violating any TOS on this. I have Google Photos auto-upload turned on.
But, knowing how stressed I was when this started, I was definitely not thinking about Google's (or Facebook's) TOS when I was making the videos, so if it had been some other condition where the affected area was the groin, like in the article, I'm pretty sure I would not have realized I'm risking my entire online presence.
Some good news to close: my son's face is showing good movement after ~10 days, so I think he'll recover within a month.
