More and more children are being bullied by mobile phones and computers according to a new survey.
Bullies using mobiles is the biggest problem, with 14% of kids bullied by text and 10% saying a camera phone has made them feel embarrassed or bullied.
The children's charity NCH carried out the survey, and they've launched a website to help kids beat the bullies.
Anyone who is being bullied can also get help by texting a special number for advice on what to do about it.
More than a quarter of the children being bullied by a mobile said they didn't know who was doing it.
The NCH's new technology adviser John Carr said: "For a child or teenager being bullied by mobile phone, it can be terrifying and feel like there is no escape.
"This new research reveals the massive scale of mobile bullying and shows how camera phones are being used by bullies to frighten and intimidate their victims."
The people doing the survey talked to 770 teenagers aged 11 to 19 about bullying.
