This was asked a couple months ago and scripts for claiming free Bitcoin 24/7 is illegal and it will only be a matter of time before they are caught. Also using scripts can be risky as you never know where the script comes from and they can steal your Bitcoin unless the person using the script creates it them self.
There are thousands of scripts on the internet that claim to help the user in some way but rather it is used the sacmmer to fetch critical data from users.
It's always better to user open source scripts or your own scritps.
