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.

oh right. another mod they took from a users created idea and never paid them royalties for....nice.

i guess it was giving freely to the community...i doubt they took his code just his idea :-/ but i see what you mean..

I have installed this on my board had it running for quite some time now, 4+ months. The other day someone called me and told me that they weren't able to register because the NoSpam question was answered wrong but that they were never prompted for a NoSpam answer during the registration process.

I checked for myself and indeed there was no nospam question...

I have unintsalled and reinstalled the product with no luck. I went through the troubleshooting and did everything that suggested which changed nothing. I went through the integration.txt and did everything but the quickregister since I believe I have quickregister disabled and one still cannot see the nospam question.
This is on VB 3.5.4

Does anyone have any ideas?

I am using this on VB Version 3.6.4 and have been using it for a while. A couple of people have emailed me because they are having trouble registered and it is telling them that the No Spam question was answered incorrectly. They stated they cannot see a question.

While on the phone with one o fthe people I logged off of the forum and went to register and I saw the No spam question just fine but he was describing the screen he was looking at and it was not showing at all.

Any reason why this would not be showing on someones specific PC? He was using Internet Explorer (as was I)

[HP10T]

I am glad I am not the only one that is having this problem. I have been trying to figure this out for the last 2 months with no response on the other thread.

Oh just checked that one and it seems to be working fine. Whats the cool wet stuff fire fighters use..

[Digital Jedi]

I just registered on your site Ron, and it showed up just fine in IE7. The question also shows up in FireFox and Opera when I check. I can't imagine whey their not seeing it.

[Boofo]

The question shows up fine. The legends don't show up though so that might be why they are saying that.
