The mother of a 6-year-old girl says she was horrified to find out her daughter had entered a "sex room" while playing a video game online targeted at children.
Peggy told Kidspot she was near her daughter while she was playing a computer game on Roblox, an online platform where users can create their own games.
She saw a "friend" inviting her daughter into a private room within their online world.
The friend, Peggy quickly realised, was actually a stranger and her daughter had entered a "sex room" within the game.
"Luckily, I was sitting next to her and noticed out of the corner of my eye that one of the characters had breasts so it made me look closer," the mother said.
"She had absolutely no idea what she was looking at, but I would hate to think about what would have been said to her."
The mother quickly told the girl to stop playing the game, reported the room and informed other parents.
The "sex room" was quickly removed.
Parental controls include the ability to block chat settings for their underage children.
According to Kidspot, many Roblox videos contain sexual and violent content, including school shootings.
Users get around the filters and controls by using "shex" instead of "sex", for example.
Roblox has been dubbed the "number one gaming website" for children.
