This is a very big problem irl and it's even worse on social media where anyone can spread malicious fake news and many foolish readers believe in it. And they will make sure to milk out in those fake stories cuz they can get away with it.
Imagine using the name of a CEO of the company of the same brand name to spread fake news and they still not get arrested for libel.
This is a reminder that you shouldn't always trust what people in social media says and always research the facts so you won't be fooled.
