How do you hack robux from roblox

Well actually im afraid of trying to hack or cheat to have robux,tix or any other things. Cuz i already heard that when a moderator looks at you hacking at cheating you get banned...And one more thing there ain't any hacks that some other people tried that became sucessful.Try to save up some tix and change it to robux by the currency exchanger.Or look up for some things for free at the Public Domain on Catalog. Hope this helps...
