PLEASE DON'T MAKE THE CHAT SO THAT IT IS GAME RELATED PHRASES ONLY!
But you need to add that report option as soon as you can. I was recently kicked out of a game because I didn't want the color green. When I went back to the room to ask for an answer they asked if I had a big ass. They said that they wanted to feel it. I don't want you to make the chat game related phrases but I don't want that happening again. I would appreciate it if you would add something where if someone says something like that you can press a button that would allow you to find the character, tap their name, tell the offence, and the game bans them. This would actually go well with your account plans.
