Popular gaming platform Roblox is under scrutiny over so-called "condo games" that could expose young users to naked figures, simulated sex and crude language. Operators of Roblox say the platform, which enables users to program their own games and play games created by others, is used by at least half of American kids under age 16. Roblox is often played on a smartphone, tablet or laptop, and enables kids to create themselves as virtual characters and explore different environments, pretend they are superheroes, raise pets and even invent their own games. Some of these games, according to an article published in Fast Company, are written in computer code that bypasses Roblox's child safety filters (known as “condo games”) and could expose children to inappropriate images and scenarios in the game.
