If you become aware of false information being shared on social media, you can correct it in a new post. This is less confrontational and embarrassing for the person who posted it. Remember that most people don't want to knowingly share false information; they probably posted it quickly without checking it first. Your correction should not be a challenge, just a new post (or a comment attached to the incorrect post) containing the correct factual, verifiable information.
You can also improve your own practice by stopping to think about what you're sharing or posting. Is it something that you can verify independently, using an authoritative, reliable source of information? If not, maybe it's better not to share until you can find out more.
Stop to check the source of the post - identify whether the account is legitimate or whether it belongs to a bot or troll. If the account is legitimate, check the credentials of the information's author or publisher.
