A title arouses outrage and the group immediately forwards it. I propose that we verify the date, source, and full text before attaching meaning to it.
In the example, an old event is presented as just happened. Emotion does not prove false, but may make the necessary questions less visible.
If the news is about identifiable people, the effect of the spread deserves even more attention. The next fix is useful, but it doesn't always reach all the recipients of the first message.
