Also as for the cussing in chat / being rude in chat situation I really don't think you should do anything about that because we already have a censor and ban/kick option. Messing with chat settings and privileges will just make take away the fun of the game as well as making it more complex and frustrating to use because of the restrictions (as some people *cough like me* like to cuss in chat).
There have also been a few people complaining that people put cuss words or something in their usernames - again I suggest you shouldn't do anything with that. It's funny and if you restrict certain usernames then it just makes the game less fun.
So as for that aspect you should keep that the same because it's not that problematic and it keeps the game's simplicity (please for the love of God don't make it like roblox or those shit games when you literally can't say shit in chat please)
