If you are wondering if Roblox is OK for a 7-year-old. It is worth noting that Roblox has an ESRB rating of 10+ years. This means that Roblox is suitable for children over 10 years old. However, that does not mean Roblox is not suitable for a 7-year-old child. But parental discretion is advised.  My children have been playing Roblox since they were 7, and I have yet to experience any problems. The helpful thing is that Roblox also has a reporting and chat filtering system where parents can limit or disable certain chat capabilities or report abuse.
