My basic cloaking script

I posted a quick and dirty cloaking tool in the tools section. I thought I might post it here too, maybe somebody would have missed it.

I just learned about cloaking today so I decided to write a quick script that tries to filter out Google?s spider via an ACL and the user-agent.

I know it?s very basic and only works for Google?s spider. Maybe you can give me some ideas so I can incorporate them into the script.
I?ll definitely be updating this and I?ll make an update in this thread when I do.

Anyways, I thought maybe somebody would have a use for it. If you have any questions, just ask.

PHP:

<?php

$bip    = new ArrayObject();
$bhn    = new ArrayObject();


/*
 *    Set these variables to the location of the file that holds the black listed IP/hostnames
 */

//$ipblacklist    = "ipblacklist.txt";
//$hnblacklist    = "hnblacklist.txt";

if(isset($ipblacklist))
{
    $file    = fopen($ipblacklist, "r");
    
    while(!feof($file))
    {
        $bannedip    = fgets($file, 1024);
        $bip->append();
    }
}
if(isset($hnblacklist))
{
    $file    = fopen($hnblacklist, "r");
    
    while(!feof($file))
    {
        $bannedhn    = fgets($file, 1024);
        $bhn->append();
    }
}

$hostname    = gethostbyaddr($_SERVER['REMOTE_ADDR']);

if(in_array($_SERVER['REMOTE_ADDR'], (array)$bip) || in_array($hostname, (array)$bhn))
{
    include("spider_content.html");
} else if(stristr($_SERVER['HTTP_USER_AGENT'], "Mediapartners-Google") || stristr($_SERVER['HTTP_USER_AGENT'], "Googlebot")) {
    include("spider_content.html");
} else {
    include("human_content.html");
}


?> 

 

Does cloaking get a site banned in Google?

 

I'm very new to this all, but from what I can gather IF they find out that you are cloaking, you will be banned.
That is, of course, IF they find out.

 

So you mean to say that cloaking is not 100% safe ... you can be caught/banned?

 

That's what blackhat is all about

 

$bannedip = fgets($file, 1024);
$bip->append();
bannedhn = fgets($file, 1024);
$bhn->append();

are these place right?
