Nearly everyone has some kind of a social media presence. Because people are willing to share personal details of their life, these social media posts may end up being used against them in their case.
If the plaintiff was injured because of negligence or an accident, the insurance companies defending themselves and their clients may try to prove otherwise. Social media activity could end up becoming vital evidence in helping insurance comapanies win when plaintiffs are not careful about what they post on social media.
For any legal case involving an accident or injury, perhaps the wisest option is to simply refrain from posting anything on social media.
