ban rate... who knows? Depends HUGELY on a script itself, too. I would say they are, if it makes the money back and some extra
All I can say is that it will have a lower ban rate than the free ones, simply because they are less used. This only applies if the said scripts have same anti-ban features.
Also an option: when you have an expensive script but get banned in 1 day - because it's just shit VS the free one, that has decent anti-ban.
well a prem script is usually going to sold w a collection of other scripts, imagine a prem zulrah script being given away for free.. would really fuck the opportunity up for everyone else that might want to bot zulrah (w a dif script).
