TikTok: how proactive it is re children's safety?

Cyber safety experts are warning the world's most popular iPhone app TikTok compromises children's safety and privacy, raising concerns about predatory behaviour, bullying and exposure to age-inappropriate content. TikTok is taking hold here - it's New Zealand's 11th most downloaded app - and has more than 500 million active users world wide. Courts in Indonesia and India have moved to ban it, and a fine has been imposed by a US court for illegally collecting personal information of children age under 13. Australian cyber-safety expert Susan Mclean tells Kathryn Ryan it would be easy for creators to be more proactive in making it safer for children to use, if only they wanted to.
