A few things can be done to fight cyberbullying and other negative behaviors on social media sites, such as:
Investigate and learn everything about the privacy settings of a particular website like Facebook, Twitter, or Instagram and make the most of them.
Be careful of what you post online. Think and decide before you make anything live.
Educate yourself and others about the downsides of social media and various precautionary measures to increase social safety.
Keep all your information personal. Update your password regularly, and don't hesitate to get help or speak out if you find something suspicious.
