You've probably read some posts from friends on Facebook and Twitter that could be considered over-sharing, embarrassing or bashes the person's boss.
A new survey shows that most people don't think about the consequences before they post.
"There are real life consequences to what people post on social media," said Kent Zimmerman, a Lawyers.com contributor.
That latest post or tweet could land you in big trouble.
A shocking new study from Lawyers.com finds that the majority of people using social media had no clue that what they posted online could have legal ramifications.
"The reason why it's a wake-up call is because the study indicates that more than half the people out there who use social media don't realize that what they post on social media can be used against them in a court of a law, and to me that's a big surprise," said Zimmerman.
Even if the post has nothing to do with anything illegal, it could come back to bite you.
Checking in somewhere online could place a defendant somewhere they shouldn't be and it can impact a case.
Social media activity can be subpoenaed.
But it turns out that younger users are wiser to the pitfalls of over-sharing.
60 percent of Facebook users between 18 and 34 believe what they post can be used in court, compared to just 33 percent of people 55 and over.
But it's not just the courtroom.
Online posts can also get you in big trouble with the boss.
"When you work for somebody you have the right not to be discriminated against your race, your gender, your sex, your ethnicity, where you were born- the protected class things that federal law protects, but you don't have the right to be stupid," said Zimmerman.
Bottom line: think before you post.
Don't share anything online that you wouldn't want the whole world to know.
