And don't take tension as you will get the victim's ID number by opening his profile and then looking at the address bar, it will be written like "id=***************" but instead of each '*' there will be a number.
But the main problem is that you wont get this software easily and even if you'll get this software then it wont be an easy task for you to crack it, so I will say that the steps are easy but getting a cracked software is very difficult but still I have a cracked one.
