Roblox games don't have an age requirement feature yet, so Restricted Mode would not do anything to prevent someone from playing Phantom Forces or the likes.

Regardless, it's clearly the parent's fault for being negligent and not bothering to actually monitor their childrens' actions online, and instead take it out on others. A testament to how awful parenting has become in modern day.
