This is the age of Social Media. Everyone seems to be on Facebook, Twitter, etc., including Hackers. Things can be attributed to you that you had nothing to do with. Other parties to litigation also are on-line and can read what you write and what is written about you. Even if you do not give them access, your "Friends" might.
In a divorce or custody proceeding, you can expect to have these and the on-line dating sites searched for your presence. You should not be there! Even the most "innocent" comments can be taken out of context and used to make you look bad.
