It goes beyond that though. There are games and in-game content that aren't being reviewed. There are claims of player skins where the characters are wearing a t-shirt with an actual photo of Charlie Kirk's death (the shot to the neck).
Anyone can make a Roblox game and publish it, and there doesn't seem to be a lot of moderations or verification going on. And you don't need to "talk", voice or text. You can emote, type on signs, and communicate in other ways.
