What type of roblox rules do you get banned for

You can get banned for breaking any Roblox rule. The type of ban depends on how important the rule is or what you have done to break a rule. If you say a bad word, and it is the first time, you will get a warning, but if you keep saying bad words, you will get a permanent ban.
If you are a Builders Club member, and you are banned, there are no refunds.
