Organisations with interactive websites likely to be used mainly by children must ensure that staff moderating the sites are not barred from working with children from October. It will be a criminal offence for an organisation to knowingly employ a barred person for a regulated role, such as moderating children's sites. ... Organisations will have to decide whether any of their activity falls within the boundaries of the new law. If it does they will need to register staff with Government body the Independent Safeguarding Authority (ISA), which will check if those people are on either list.Source: OUT-LAW
