My son plays Roblox and this is definitely a big issue. I basically had to turn off his filter so he could play the game. Otherwise, the chat looks like this:

Player1: "Can you promote me?" Player1: "Did you see that?"

Player2: "Yeah, just send me a message" Player2: "Did you see that?"

Player1: "Thanks!" Player1: "Did you see that?"

Pretty frustrating, even for a parent. Seems like their filtering technology is just a total piece of junk.
