It is easy for an individual or a group to bully you online so think about who you give your mobile number to and who you let on to your Facebook, Twitter, Snapchat or WhatsApp profile.
Online bullies might be somebody you know or they may not tell you who they are. If you don't like the messages you are getting from someone, you can block them or remove them from your contact lists. You can also report them to your mobile phone or your social network provider. If you are being bullied in this way and you're not sure what to do, ask for help and look at the External links section for further information.
