Fines of up to €2 billion are being proposed by the European Parliament as part of a series of new data protection regulations to combat cyberbullying.

A conference in Limerick has heard contributors appeal to companies to do more to promote their online data safety and protection features.

Research by the UK based anti-bullying charity Beat Bullying shows that 1,700 young people have considered suicide as a result of the torment caused by bullying and bullying online.

Companies such as Facebook say they take reports of harassment and bullying on their websites very seriously, and have improved their privacy controls and how users can manage their information.

However, those working with victims of bullying and harassment say these safety features are of little use to young people if they do not know about them, or how to use them.

Major reform of data protection legislation across the EU is being considered by the European Parliament.
