The risk is when the whole system detects you using a kind of exploit that makes you win everytime.
First of all it isn't any hack or illegal method.
So what is it at the end ? Voucher says it isn't an exploit.
Since it isn't an exploit, why there is a risk by only using your script ?

There is a method on how you can avoid the system detection anyway so yeah its true a very very low risk. And it is not a script btw
