What to do if you are bullied online
A grandmother from Devon describes herself as a troll hunter, tracking down cyber bullies.
Sandy spends her days helping teenagers who receive online abuse and tipping off police about the people who are doing it.
It's because two years ago Izzy Dix took her own life and her mother believes she was targeted online.
Steve Shepherd from the Exeter-based UK Safer Internet Centre says the problem of cyber bullying is 'getting worse'.
Steve spoke to ITV's Ian Axton about what you should do if you think you are being targeted online.
There are 32 Safer Internet centres across Europe and many other organisations raising awareness of online bullying and providing information on what to do if you are a victim.
Organisations you should report to.
Grooming or other illegal behaviour: if you want to report someone who is behaving suspiciously online towards a child, you should in an emergency contact the emergency services by calling 999, or otherwise make a report to CEOP, the Child Exploitation Online Protection Centre
Child sexual abuse images: If you stumble across criminal content online, you should report this to the Internet Watch Foundation at www.iwf.org.uk/report. Criminal content in the UK includes child sexual abuse images, criminally obscene adult content as well as non-photographic child sexual abuse images.
Online terrorism: You can report terrorism related content to the police’s Counter Terrorism Internet Referral Unit at www.gov.uk/report-terrorism.
Hate speech: Online content which incites hatred on the grounds of race, religion, disability, sexual orientation or gender should be reported to True Vision at www.report-it.org.uk.
