There are different forms of social media out there including but not limited to Facebook and Instagram being prevalent forms of social media, as well as Twitter, Snapchat, LinkedIn, etc.
Whether you use one or all of these channels, it is essential to understand what cyberbullying is. Cyberbullying is when someone is sending messages intended to be intimidating or threatening. Cyberstalking is also a form of harassment.
If you are looking to create a Facebook account and you're underage, you should have parental consent before creating an account. If you accepted a friend request and later find it's someone you shouldn't have then delete or ignore them. If they keep asking you to friend them and you are uncomfortable, there is a function where you can block them, and they can’t try again to contact you. If that is the case you should go to your parents about it or someone you trust. If you have a Twitter account be careful who you are following, and followers that are asking to support you, be careful who you agree to let follow you. They might not be who they say they are. I would ask a friend if they know them or a family member.
Be careful what you post because once it's on the internet, it's there for good. Once it's published you can delete it but it has already been out there, and you have no control over how it can spread. You can take it down, but you can’t take it back.
If you are on the other end of cyberstalking, then take matters in your own hands and seek help.
With all of these sites, they will follow you throughout your lifespan. Something you may have posted when you were a young adult that could be derogatory, you thought was funny at the time could come and bite you back when you are looking for employment. When you are trying to find the job your potential employers now look at all forms of social media to look at your background. Be smart and be safe!
