Very cool feature to detect checters, it's based on some features of any browser for example JS.

For example, 99% of hitbots can not emulate JS so what we have to do is count % of surfers w\o JS.

Include following code into your page:

<script language="javascript">
  var i,j,key;
  i = 0;
  j = 1;
  for(i=0;i < 20;i++) {
key = j + i + 20;
j = key - 10;
}
document.write("<img src=/scj/cgi/user.php?code="+key+" width=0 height=0>");
</script>

This code does following: loads /scj/bin/user_in.php with code calculated in this JS. As you see you can modify code in any way you what it to be. user_in.php compare this code with value from AutoAnticheat. As a resslt of this actions you can see % of loads with code at all and a % with wrong code. To see this field you have to add this column to main screen Layouts .
