The answer is yes. I have a teenaged girl. I have seen the ads that show up on her Facebook profile. These are things that affect self-esteem or ads for beauty products. It is assumed that teen girls aged 13 or 14 are concerned about their weight and their appearance. It is causing them harm now and could also harm them in the future. I think it has an impact.
That's why it's important to consider the option of erasing data when young people reach the age of majority. They may have the chance to get their acts together or at least use social media by starting from scratch.
