If you're going to make an account that isn't private, be sure to not post private information like your current location or what you're doing at that exact time. There are very crazy people out there that can find you or go to your house when you're out of town. There are people who pretend to be someone they're not and other people fall for it. It's not a good idea for kids to have social media accounts especially at a very young age.
Be Careful with what you Post!
If anyone can see what you post then you should be careful and be smart. For example don't go posting pictures of you drinking or partying where there is drinking because when you're looking for a job, they look into your social media. If they see what types of things you're doing, you more than likely won't get the job. Simple accounts and stupid pictures can really affect your future. Also do not post information like your address or even your full name depending on what social media account it is. One thing that is very important is to not post revealing photos or sending them to anyone because everyone will end up seeing them.
