Theres no safe way to use hacks. But, the only way you get caught is if someone records you and sends it to deca. I guess if you have previous history of being banned for hacking it might not require as much proof the next time though.
The point im making is that you will only get banned if others report you. If you use obvious hacks around large groups of people (like oryx castle and shit) you run the risk of being caught.
Do it at your own risk, its not on anyone else but you to decide if its "worth it".
