Miscellaneous Hacks - NoSpam! - an alternative to CAPTCHA images

This hack is for vBulletin 3.6.x. For 3.5.x, please use the one provided in this thread. If you are using 3.7.x, you must use the one in this thread.

This simple hack is meant as a replacement for the default CAPTCHA system in vBulletin. There are two main reasons one might want to do this: firstly, new technology is constantly being developed to crack CAPTCHA images and make spam accounts anyway, and secondly, the more secure the CAPTCHA, the more difficult it is for genuine users to tell what the numbers in the image are. There is also the issue of visually impaired users, and the fact that not all servers are capable of generating CAPTCHA images.

So what does this hack do instead? It asks a question. Any question you want. That's the best part: YOU make up the questions, which means that every forum is unique, which means that it is impossible for spambots to be simply programmed to bypass it at all forums with the hack installed. You can make one or many questions - if you make many, the hack will pick one at random when a guest attempts to register, search, post or send mail through the Contact Us form. Their input is compared with your specified answer, and voil?, if they get it right they're pretty much guaranteed to be human. If they get it wrong, they're given an error message.

It doesn't have to be a complicated question. Heck, you can just make it "Please type 'blah' into this box." Or you can go with inserting a simple image with HTML and ask what is shown on the image. Or you can ask them to tell you two plus two. It's up to you. In fact, this can also be used as a means of forcing people to read the rules by asking for a certain password found there, or if your forum focuses on a specialized subject, ask a question concerning the subject that all your genuine users will be able to answer, but a random troll or "CAPTCHA-sweatshop-reader" will be scratching their head over.

It's simple to install, too: just one product to import, and that's it.


VERSION HISTORY:

3.0: Added functionality to allow users to specify which pages should use NoSpam!.
2.0: Extended the NoSpam! functionality to guest posts, guest searches and guest "Contact Us" in addition to registration.
1.1: Made template edit automatic (with thanks to Cole2026), added ability to have more than one answer to each question, and made answers case insensitive. To upgrade, I recommend undoing the template edit so you won't have to worry about it anymore (replace $nospamfield in the template register with $imagereg, or if you added $nospamfield above $imagereg, just remove $nospamfield altogether), and then reimport the product through the Admin CP (making sure that Allow Overwrite is set to On).
1.0: Initial release.


INSTALLATION:

Please download NoSpam!.zip, not product-nospam.xml, for the tested version. product.nospam.xml is NoSpam! 4.0 adapted blindly to 3.6, i.e. by editing the XML file for the 3.7 version without actually testing it on a 3.6 board. Theoretically it should work, but I cannot guarantee it at this time. If you download NoSpam!.zip and unzip it, it will contain another file called product.nospam.xml, which you should use.

1. Import product-nospam.xml through the Admin CP product manager.
2. Go to your vBulletin options in the Admin CP and select NoSpam! Settings. Once there, turn the system on and input your questions and answers according to the instructions there.

The system should now be functional and running.


UNINSTALLATION:

Just uninstall the product through the Admin CP.


SUPPORT:

Full support will be given here in this thread. All suggestions are welcome.

Thank you and please click "Mark as Installed" if you like it.

I tried , But it wants me to edit my Quick_register in the Templets? I don't have it in the Templetes?

[wideopen]

Someone's gotta know the sollution? No one can register on my site? Help.

I guess I found the most effective way to keep out spam...Let no one register, Can anyone tell me what Templete had to be modified? I'm grasping for anything to be able to register members again? HELP!

Image Verfication? That has nothing to do with this mod.

I just registered on your board, and it worked fine.

I have been running the NoSpam! plugin since my first usage of vB (which was at version 3.5.4), and I can say that it has been THE most useful plugin for me, too.

(even with super-simple questions: 0 spambots in over 18 months)

I'm not very active with modding vB anymore, so its a pleasant thing to see this functionality included in the stock code for the coming version.

(if not, I would have waited with installing 3.7 until an updated NoSpam! would have been released - did that with 3.6 too)

Works perfectly with 3.6.8 Patch Level 2,
thank you!

[mistapuggs]

Same here. This was 100% effective on spam registrations on my board. Seriously, 100% Big thumbs up from mistapuggs :up:

[budatalk]

Finally what I needed, thanks a lot!!!

This is a great mod, easy to install and setup. Hopefully this will weed out all excessive amount of spam users that register on my forums.
