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.

True. You need to use the modified one called 3.7. Find it in this post: www.vbulletin.org/forum/....1548655

I upgraded from 3.6.8 P2 to 3.7.1 P1 a week ago. I lost out on quite a few new members because of the 'error' of the previous version of NoSpam!

Well, since adjusting it to XXP's version, it's been working great.

Thanks again XXP!

I'm running 3.6.8 PL2 and haven't been able to get any questions to appear on the registration form.

I've read the installation instructions. edited the register template to include $nospamfield
I'm not using Quick Register but tried the edits suggested in the integration instructions and still wasn't able to seem to get any verification questions to appear.

I've uninstalled this mod, but will check back to see if there are any good ideas here.

I see some other people are having similar problems.

Hello, and sorry about my absence. I have just released a new version of NoSpam! for vBulletin 3.7; it is linked to at the top of the first post of this thread. I have also attached to that first post an experimental NoSpam! 4.0 file which could theoretically fix edward hamilton's problem (and that of others who run into the same issue). It is untested on 3.6, however; it will not delete your database or anything, but it might simply not work. Anybody who has a 3.6 board and would be willing to try it and report on whether it works would be greatly appreciated.

Perfect add on.

Zero spambots since installation.

That's OK. No need to say 'thanks'. And thank you for responding to emails and attempts to contact at your site. No problemo, as they say.

Cool mod. I installed it on my Webmaster Forum.

How would you use an image as was described above and paraphrased here:

"Or you can go with inserting a simple image with HTML and ask what is shown on the image"

[rwoscott]

Nice Mod. Easy to install and use.
AND works a treat.

Thanks.

Installed on 3.6.2. It was so easy. Much better then Captcha...often users can not well read the letters (lower case, upper case)...It is much easier now!

Tx for sharing this nice piece of software.
