vB Version: 3.6.1 Rating: (180 votes - 4.84 average) Installs: 1984
Released: 17 Apr 2008 Last Update: 27 Jan 2010 Downloads: 6819
Not Supported DB Changes Uses Plugins Auto-Template Additional Files Translations External Content Is in Beta Stage  


This provides access to a RBL type system for forum admins, listing known spam IP / email / usernames. The RBL database is provided by You do NOT need an API key from the website in order to access the database. only to submit data if you should wish to do so.

At the point of user registration, the mod checks if the IP number / provided username / email addresses appear on a block list and can block the registration.

Whilst this isnt the most perfect way to stop all forum spam, its another step that spammers have to overcome.

VB4 here
Its the same code, it works in 3.54 to 4.0

What it does

It checks with a remote database of known forum spammers. Their IP number, email address and forum username are tested and based on your configuration, you can reject / log / accept user registrations based on what you get back.

This version doesnt have
- whitelisting or the ability to submit users to the database but it will within the next week.
- automatic user deletion / post / PM purging. There are good tools out there already, this does something else.

Instructions are included in the installation.txt file - PLEASE read it first and dont forget to actually upload the files in the upload folder, otherwise it WILL kill your registration progress and you wont see the log file options in admincp. You do not need to download the product-vbstopforumspam-3.54.xml file unless you are using a vBulletin version older than 3.6.0

Changes to vB
- 3 new database tables
- 2 database table alternations
- No new templates.
- 2 Hook (register_addmember_process & register_addmember_complete)

Ive tested it but had feedback that it works with versions as old as 3.6.2... Support should go back to older versions, as long as they have hook support for register_addmember_process / register_addmember_complete

Known to work - tested by me
- vBulletin 3.6.8 on Apache 2.2 / PHP 5.1.2 on Linux using cUrl
- vBulletin 3.7 Gold on Apache 2.0 / PHP 4.4.3 on Windows without cUrl (template changes wont work on 3.7 - thats in the next version with auto template changes)

For code to submit spammers to the database, check this post for code changes

Reported in the thread to work
- 3.6.1, 3.6.2, 3.6.9, 3.6.10, 3.7.0, 3.7.1, 3.7.2, 3.7.3, 3.74, 3.80, 3.81, 3.82, 3.83, 3.8.4, 4.0beta3

If you have 3.54, then you can use the product-vbstopforumspam-3.54.xml file attached instead of the one in the ZIP file, which will allow older vBulletin versions to access this mods' features. I personally havent tested this version, its a user contribution, thanks to Darrell Mobley, that changes the way the XML works when imported into older versions.

Installers should remember to refresh their ACP navigation window when they first install it so they can see the new log file menu item.


Future versions
- Automatic integration into vBulletin to add users to the database from a form
- Whitelisting of username / IP / email addresses
- AJAX integration to allow for lookups from within the users profile
- Decreased remote query count from three per user to one per user.

Versions / Changes

0.1 Initial Release

0.2 pedigrees special brew birthday release.
- Small security update. If you have 0.1 installed, download 0.2 and replace your existing functions_vbsfs.php with the one in the archive. It just tests to see if its running inside the VB framework before anything else. This is what happens when you code at 2am after drinking wine

- stopped it processing valid registrations twice
- moved all non-function code into the plugin. Not a big one as 0.2 basically did that
- fixed a typo in the log pruner that stopped it working (404)
- removed unused fields from the database for people with mysql that doesnt support varchar > 255 (ie mySQL4). If you have 0.2 installed and dont need to prune your logs just yet, you dont really need to install this version but can instead wait for 1.0 unless of a massive security update.

- logs registrations that arent/wouldnt be blocked
- fixed XML errors when username has a space it in
- tightened up the cache so that it doesnt test a username against an email name to give a bypass result (for when a username is an email address that isnt banned where the email address is)
- fixed some basic logic errors in the PHP

- Should work on PHP 4.4 now - rewrote the XML with PHP4 in mind (tested on Apache2.0/PHP 4.4.3)
- Fixed a caching system where data wasnt being updated correctly which could cause a remote query when one wasnt needed
- Possible false negative situation when a spammer was blocked due to being down who then visited again when it was up but within the cache expiry time
- Remote query failure when the result page isnt XML should work a bit better now. It does a very basic test for valid XML results.
- Fixed log purging (again) and it should actually work properly now.
- No longer requires PHP5
- The log viewer now links to a user profile when registration is allowed.

v0.61 - Removed a template change that was invalid vBulletin code. The package you download will still say its 0.60 however

NB : When upgrading from any version to 0.6, you must remove and then add the plugin due to changes in one of the database tables

You need to have an API key from in order to submit data, its free and easy to get... You DONT need an API key in order to use this mod however, only to submit spammer data.

Issues are
- The usergroup permissions / view details etc DONT work. I jumped the gun and put the permissions controls in there before I put the code in. Please delete the includes/xml/bitfield_vbstopforumspam.xml file and rebuild your postbit

- Follow the instructions in the zip file, that includes upload the correct folders
- ONLY download the 3.54 xml file if youre using a vbulletin version prior to 3.6.0. use this file to install the mod instead of the xml file in the zip file.

Thanks for your support pedigree. Weirdly I was unable to find the code that was supposed to install during 0.6 in MEMBERINFO So nothing needs to be done.. Great job and keep up the good work.

Well, this is good news (for this mod anyway) After the tragic lose of the author who write the One touch ban and cleanup mod, Ive been in contact with his brother who said that I can include the code in the next verson, so expect to see a selectable list of users/post by ip/subnet/email address where you can perform actions against them in batch mode... select all users from the same class-C subnet and one click cleanup and ban them all.

To make it work in mySQL 4.0...

Replace in functions_vbsfs.php

Thanks for this great mod. We installed on our forum last week and have been able to stop 30 spammers. Our site is a family oriented site and given the graphic nature of some of this spam, your mod has been a great help.

Keep up the good work!

Thanks for this mod. I have extended it to the sendmessage.php form for myself and plan on using it as a SPAM filter for our admin email accounts (using vBMS) once I get the time to code it.

I have been testing this mod on 3.8 for a little over 3 weeks.. and I have to say it is VERY VERY good.

I get logs with all actions taken and it blocks about 20 people a day, never once blocking a sincere new member...

Thank you so much!
