Before you come here to judge the script keep in mind that scripting is always a risk.
Czar is a very talented scripter and I'm sure he is making everything in his power to prevent bans. I have used his script's without problems so far.
Research about scripting before doing it and never ever use scripts on an account you worry about losing.
If you had scripted before and got banned, there is a high chance that your HWID or IP address is flagged (or both). If it is flagged you have pretty damn high chance to get banned no matter what you do.
