Do important people in your life talk with you about the dangers of certain online behavior?

Many people in my life do talk to me about the dangers of certain online behavior. Every time that I am on social media my parents aware me the dangers of cautious things, especially my mother. My mother hates the internet. She doesn't like me to have a Twitter, an Instagram and etc,. Whenever I post something on any account that I have, my mother is strict of the pictures that I post.
