So, suppose you take a picture of the sea and some flat earther reposts it as proof that the earth is flat. You're ok with FB putting a note on your picture, if anyone wants to like or share it they get a little nag beforehand, further posts you make are placed under additional scrutiny and not shown on the feed? That's giving a lot of power to the wingnuts.
No, and you're stretching... I'm not a scientific journal for one thing..
But if I was, and if I posted a picture of the sea, saying I was performing an experiment to measure the circumference of the earth.. Then yes, missing context label would be relevant. I wouldn't claiming that the Earth is flat, and context outside the picture would account for why 1 data point my suggest otherwise.

I'm not sure the 'missing context' label affects visibility like others do.
