Roblox is discontinuing private messages on October 7. Communicating with other players in the game itself will only be possible via Chat following the change.

Roblox allows players to communicate with each other using various means. While text messages are the most common way to do so, some players prefer to use the voice chat.

On Roblox, you may block someone in a few different methods, such as through their profile, the chat tool, or by reporting them for unacceptable behavior.
