If you are genuinely injured and cannot perform certain activities of daily living but you are actively posting on social media things that show you are very active socially, then either one of these things are true: you are not genuinely injured, or, you are exaggerating your social media presence.
People who are genuinely injured should stop posting anything on social media. Do not delete anything but just don't add misleading information to any site.
Insurance companies love to see your inconsistencies. They will, sooner or later, be able to discover what you post.
So, just like that Capital One TV commercial that says, “What's in your wallet?” you will be asked, no doubt, “What's on your social media platform?” No one likes a hypocrite. Be truthful but be careful as well.
