Everything you write about you is important, but what you write about others or to others is important too. Your attitude on social networks could be negative for your. An offensive comment, an aggressive retweet are part of your personal data and remain linked to your digital profile.Don’t forget that what you write commits yourself and that you are responsible for what you write.
