Nefarious game makers appear to be leveraging a chat-based Roblox exploit that results in automatic account bans for unsuspecting users.

A lawsuit claimed that Roblox enabled a girl to be exploited. According to the lawsuit, an adult man who met a young girl on Roblox encouraged her to send sexual photos of herself.
