I want to create a web app.
User will have an account with a link look like : mysite.com/user.php?user=19846
If anyone click on their links, they will get points
But how to prevent using softwares which can click on their banner automatically.
The first time, i think it should use session, cookie, or defining IP ($_SEVER) but all of them are useless (they can change IP, delete cookie easily) !!!
I don't know what i can do ????
