Prevent known spammers

Recommended Posts

This code prevents known spammers (checked against the stopforumspam.com email database) from registering.

I've used it in core/modules/Registration/Registration.php within the ProcessRegistration function, as so:

// Check email for known spammer
$url = 'http://www.stopforumspam.com/api?email='.$data['email'];
$file = new CodonWebService();
$contents = $file->get($url);
$response = simplexml_load_string($contents);

if($response->appears == 'yes'){
$spammer = true;
} else {
$spammer = false;
}			

if($spammer){
$this->set('message', 'Your email appears on our spam database, we therefore assume you are a spammer and are rejecting your registration request. If you feel this is incorrect please contact us.');
$this->render('core_error.tpl');
return false;
}

It could be condensed a little, but I feel this makes it easier to understand.

great :) where in ProcessRegistration function should that code pasted?

I put it directly after the following:

$data = array(
			'firstname' => $this->post->firstname,
			'lastname' => $this->post->lastname,
			'email' => $this->post->email,
			'password' => $this->post->password1,
			'code' => $this->post->code,
			'location' => $this->post->location,
			'hub' => $this->post->hub,
			'confirm' => false
		);

As long as it's after this part it's fine, but don't put it too far down because it'll create the user before checking...

Odd, I think I've been receiving the same error...

When I go to the page I get a normal response:

<response success="true">
<type>email</type>
<appears>no</appears>
<frequency>0</frequency>
</response>

yet it seems we're being sent something completely different when it's loaded in the script :S

Will go see if they've made changes to their API terms or something.

Update: I just printed the contents and I'm getting a 403 Forbidden error...

Are you on fivedev?

I have a feeling they may have blocked the fivedev server IP. I wouldn't know why seeing as we'd only be using it for registrations which is ok (they block if you use it too regularly - every visit to your site).

Either that or for some reason it's a problem with our end?

it might not be working... I see that they have the API Usage limits.

I'll write something up some kind of a status checker tonight to see if the feature is actually working.

I done that as well, I can get the code together and post it here in later tonight. :D

the blocking IP won't be that realistic since it would require a core change. I won't go into it.

If you were being use limited it would return a 403... that's what the problem was before ^^^

It's purely down to whether the person has been reported as a spammer yet or not. Obviously you're getting them before they've been added...

Put in the same place what Tom said on the first post.

IP Check to see if spammer.

 // Check IP
 $getIP = $_SERVER['REMOTE_ADDR'];
 $url = 'http://www.stopforumspam.com/api?ip='.$getIP;
 $file = new CodonWebService();
 $contents = $file->get($url);
 $response = simplexml_load_string($contents);
 if($response->appears == 'yes'){
	$spammer = true;
 } else {
	$spammer = false;
 }					  
 if($spammer == true){
	$this->set('message', 'Your IP Address appears to be in our spam\'s provider\'s database, if you think this is not correct, please contact us.');
	$this->render('core_error.tpl');
	return false;
 }

A more effective solution is to check BOTH email and IP:

// Check email & IP for known spammer
$url = 'http://www.stopforumspam.com/api?email='.$data['email'].'&ip='.$_SERVER['REMOTE_ADDR'];
$file = new CodonWebService();
$contents = $file->get($url);
$response = simplexml_load_string($contents);
$spammer = false;

foreach($response->appears as $appears){
if($appears == 'yes'){
	$spammer = true;
}
}				  

if($spammer){
$this->set('message', 'Your email address or IP appears on our spam database, we therefore assume you are a spammer and are rejecting your registration request. If you feel this is incorrect please contact us.');
$this->render('core_error.tpl');
return false;
}

(Not tested)

I have added this script to my VA as well as I was getting the same problem with the roster filling up with spam accounts and have not had a real issue since. I also added a quick email function to send me an email each time a registration is rejected just to see if it was working and it is rejecting on average 10 a day from my site. No matter how detailed you get there will always be something that gets through but that is what website management is all about.

The code I am using including the email function

// Check email for known spammer
$url = 'http://www.stopforumspam.com/api?email='.$data['email'].'&ip='.$_SERVER['REMOTE_ADDR'];
$file = new CodonWebService();
$contents = $file->get($url);
$response = simplexml_load_string($contents);

if($response->email == 'yes' || $response->ip == 'yes'){
  $this->set('message', 'Your email or IP address appears on our spam database, we therefore assume
	you are a spammer and are rejecting your registration request. If you feel this is incorrect please contact us.');
  $this->render('core_error.tpl');

	//send email that spam registration rejected
	$email = 'your email address';
	$sub = 'Spam Registration Rejected';
	$message = 'Spam pilot registration rejected using email '.$data['email'].' and
		 IP address '.$_SERVER['REMOTE_ADDR'].' on '.date('m/d/Y', time()).' at '.date('g:ia', time());
	Util::SendEmail($email, $sub, $message);

return false;
}
//end spam check

Try it like this, I adjusted the structure some so it should work on any phpvms site.

// Check email for known spammer
$url = 'http://www.stopforumspam.com/api?email='.$data['email'].'&ip='.$_SERVER['REMOTE_ADDR'];
$file = new CodonWebService();
$contents = $file->get($url);
$response = simplexml_load_string($contents);
$reject = FALSE;
foreach($response->appears as $data)
{
	if($data == 'yes'){$reject = TRUE;}
}
if($reject == TRUE){
		$this->set('message', 'Your email or IP address appears on our spam database, we therefore assume
			you are a spammer and are rejecting your registration request. If you feel this is incorrect please contact us.');
		$this->render('core_error.tpl');
		//send email that spam registration rejected
		$email = 'Your Email Here';
		$sub = 'Spam Registration Rejected';;
		$message = 'Spam pilot registration rejected using email '.$data['email'].' and
			IP address '.$_SERVER['REMOTE_ADDR'].' on '.date('m/d/Y', time()).' at '.date('g:ia', time());
		Util::SendEmail($email, $sub, $message);
return false;
}
//end spam check

I had changed some things from pulling it out of my VA and inadvertently reassigned the $data variable. Try this;

// Check email for known spammer
$url = 'http://www.stopforumspam.com/api?email='.$data['email'].'&ip='.$_SERVER['REMOTE_ADDR'];
$file = new CodonWebService();
$contents = $file->get($url);
$response = simplexml_load_string($contents);
$reject = FALSE;
foreach($response->appears as $row)
{
	if($row == 'yes'){$reject = TRUE;}
}
if($reject == TRUE){
		$this->set('message', 'Your email or IP address appears on our spam database, we therefore assume
			you are a spammer and are rejecting your registration request. If you feel this is incorrect please contact us.');
		$this->render('core_error.tpl');
		//send email that spam registration rejected
		$email = 'your email here';
		$sub = 'Spam Registration Rejected';;
		$message = 'Spam pilot registration rejected using email '.$data['email'].' and
			IP address '.$_SERVER['REMOTE_ADDR'].' on '.date('m/d/Y', time()).' at '.date('g:ia', time());
		Util::SendEmail($email, $sub, $message);
return false;
}
//end spam check

Just change the email in the spam part - in the above code, it shows as YOUR@EMAILHERE.COM
