Very cool feature to detect checters, 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/cgi/user.php with code calculated in this JS. As you see you can modify code in any way you what it to be. user.php compares 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 (user vars) to main screen Layouts .
