NSPCC safer technology expert Claire Lilley said: "However, these changes alone are not going to solve the problem of online bullying. And, while they are being implemented, children and young people are likely to continue to suffer.
"Parents can help by having regular conversations with their children about what is and isn't OK online, and encourage them to seek help if they are being bullied, blackmailed or see anything that upsets them.
"It's important that young people know that if they need somebody to talk to, they can call ChildLine on 0800 1111."
