vB Version: 3.6.1 Rating: (180 votes - 4.84 average) Installs: 1984
Released: 18 Apr 2008 Last Update: 27 Jan 2010 Downloads: 6820
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.

Everything is updated on the server, we're running vB 3.8.0 and while the plug-in is working, we are still getting about 20-30 very strange database errors per day. When the plug-in is shut off, it all stops, so it's something being driven by vbStopForumSpam.

They all have the "Swedish" and "Latin" notes in the errors, and we can't figure out what is causing them. I'm going to attempt to find 3.8.7 forum software when I get a chance today, but their current system for older software updates leaves me itch, so we'll see what I can come up with. It might help the issues with the database errors.

If anyone else notices something obvious, I'd appreciate any input.

At some point in the past couple days (since 12/28) guests have not been able to register because they are apparently being tagged as a spammer. I confirmed this by trying to register myself and also was denied.

Has anyone else had this problem in the past couple days?

I checked my info against database and it is not in their database. So registration should be allowed.

How are you guys dealing with members contacting you saying they're not spammers but can't sign in? Obviously they were banned elsewhere, but I'm afraid I'm missing out on many members because of this.

I noticed the same thing beginning last week.
I installed spam-o-matic thinking something was wrong.
Same results with that.

It just seems that these new registrants are not listed in the sfs database yet.

If you're running VB4, what you're missing is Spam-o-Matic. Works great, adds an excellent ban and report button to the forum, and is currently supported.

I definitely would (and do) choose it over this one if you're running VB4.

Hi guys,

I created a plugin for this product in order to manually report a user from inside the admin control panel, while seeing the user's full profile/editing screen.

I needed that in order to manually report offenders that were blocked by the Multiple Account Registration Prevention product and automatically moved to the "Users Awaiting Moderation" group.

I hope this little add-on is useful for other user who need a reporting tool inside the admin CP.

PS: You need to import this file as a PLUGIN and not as a product.

Thumbs up

Nice addition... instead of just deleting the users that make it through the filters, we can add them. Excellent.

Now, all we need is a way to whitelist those users who are trying to register and can't because their preferred username is on a blacklist somewhere keeping them out.

This blocks too many legitimate users. Unfortunate. The User Agent block works the best by blocking IE6 and below and well as other bot spiders.

Only if you have 'User Names' enabled. Otherwise, it denies registrations from people on the SFS spammers database - what is there not to like?
