As mobile instant messaging services are very popular with children, the chat rooms provided by these services are mainly filled with children.
This then provides an ideal hunting ground for pedophiles who remain anonymous while using the chat service.
Several cases have been reported in the media where adult men successfully lured teenage girls from mobile chat rooms to a meeting in the real world with the aim of sexually exploiting them.
This is termed "grooming" and is a criminal offense as defined in the amended Sexual Offences Act.
Join any anonymous chat room, or if you are technologically challenged, ask someone to show you a chat room on their mobile phone.
