Hello ROBLOX,

Recently, I caught my 8 year old son playing a violent game on ROBLOX. I took the computer from him immediately and put him on a time-out. Meanwhile, I came to the horrifying discovery that, while the game he was playing was called "Phantom Forces", there were countless other violent games that I just was disgusted to see on a kids website. I have decided to make sure my son never plays ROBLOX again until these games are banned and I am encouraging other moms to do the same.
