Social networking site Ask.fm has unveiled changes to make its site safer after recent online bullying cases.
It said it would view all reports within 24 hours, make the report button more visible, and include bullying and harassment as a category for a report.
It said some of the changes would be live on the site by September.
The father of Hannah Smith, 14, who is believed to have killed herself at home in Leicestershire after she was bullied on the site, welcomed the changes.
