THIS MODIFICATION SHOULD NOT BE USED WITH VBULLETIN 3.7+ AS IT IS A DEFAULT FEATURE.

Keywords: reCAPTCHA, CAPTCHA, spam, register

Description:
This modification will replaced the default vBulletin registration CAPTCHA with the newer, more advanced reCAPTCHA.

What is CAPTCHA/reCAPTCHA?:
A CAPTCHA is a program that can tell whether its user is a human or a computer. You've probably seen them colorful images with distorted text at the bottom of Web registration forms. CAPTCHAs are used by many websites to prevent abuse from "bots," or automated programs usually written to generate spam. No computer program can read distorted text as well as humans can, so bots cannot navigate sites protected by CAPTCHAs.

About 60 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that's not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. What if we could make positive use of this human effort? reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into "reading" books.

To archive human knowledge and to make information more accessible to the world, multiple projects are currently digitizing physical books that were written before the computer age. The book pages are being photographically scanned, and then, to make them searchable, transformed into text using "Optical Character Recognition" (OCR). The transformation into text is useful because scanning a book produces images, which are difficult to store on small devices, expensive to download, and cannot be searched. The problem is that OCR is not perfect.



reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly.

But if a computer can't read such a CAPTCHA, how does the system know the correct answer to the puzzle? Here's how: Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one. The system then gives the new image to a number of other people to determine, with higher confidence, whether the original answer was correct.

Currently, we are helping to digitize books from the Internet Archive.



Installation:
  1. Download and unzip the recaptcha101.zip archive.
  2. Upload the functions_recaptcha.php to your /includes/ directory.
  3. Import the product-recaptcha.xml via the Product Manager.
  4. Obtain a FREE public and private reCAPTCHA key here.
  5. Make any desired configuration changes via AdminCP > vBulletin Options > reCAPTCHA Options
  6. Make a backup of your register.php file, located in your forum root.
  7. Perform ONE (1) of the following methods:
    • Method A:
      • Download the register-patch.zip archive, extract, then upload the register.patch file to your forum root, then apply the patch:

        *Note: Please note that this method requires a basic understanding of UNIX shell commands and requires shell access to your host. If you do not have either of these or you are unsure how to use GNU patch, I highly suggest performing Method B instead)


        Block Disabled:      (Update License Status)  
        Suspended or Unlicensed Members Cannot View Code.

        This will perform the file edits automatically. Once finished, you may delete the register.patch file.
    • Method B:
      Perform the following simple file edits:
      • IN register.php:
        1. FIND:

          Block Disabled:      (Update License Status)  
          Suspended or Unlicensed Members Cannot View Code.

          REPLACE WITH:

          Block Disabled:      (Update License Status)  
          Suspended or Unlicensed Members Cannot View Code.

        2. FIND AND REMOVE:

          Block Disabled:      (Update License Status)  
          Suspended or Unlicensed Members Cannot View Code.

        3. FIND:

          Block Disabled:      (Update License Status)  
          Suspended or Unlicensed Members Cannot View Code.

          REPLACE WITH:

          Block Disabled:      (Update License Status)  
          Suspended or Unlicensed Members Cannot View Code.


NOTE: YOU MAY ALSO REPLACE THE CAPTCHA DISPLAYED TO GUESTS WHEN USING THE "CONTACT US" FORM BY FOLLOWING THE INSTRUCTIONS HERE.

Comments:
As with all my hacks, this modification is provided free of charge. However, if you find this product useful and have money burning a hole in your pocket, feel free to make a small donation, I won't mind.. really.

Version History:
  • 1.0.0 - Initial release, here's to hoping...
  • 1.0.1 - Woops! Forgot to include a aesthetic template edit in the original release. All is well, simply redownload and overwrite the XML. That's it!
  • 1.1.0 - Added alternate language support. Now various reCAPTCHA tags and text will be displayed in your selected language. Also added a fieldset to the automatic template edits around the display block for a more uniform look (thanks DOCTOR DAN!).

Currently Known Bugs:
  • None

* Please note that this modification was developed on a forum with a userbase of 1 (myself). I've tested it for basic functionality but I cannot guarantee functionality or behavior on your forum. So, please -- make backups before installing this product!

Hello hundreds of people, here's what you needed.

Instructions:

1. Go to: http://recaptcha.net/ and sign up, write down your public and private key.
2. Go to your forum administration panel
To turn on recaptcha:
Admin CP -> vBulletin Options -> Human Verification Manager
3. select the recaptcha option and click submit.
4. When the page refreshes, the next step you need to do is provide that public and private key. Now you should be set up.

Support
1. Go to: http://www.vbulletin.com/forum
2. Register, (because you can't search until you do)
3. Log in and use the search function to search for 'recaptcha'
4. You will find dozens of posts, read them all to see if your questions are already answered.
5. If not answered, feel free to post.
6. Wait for support.

Best regards

There is no recaptcha option. Maybe it was removed?

The recaptcha website is pointing to this thread.

3.8.2 already has the reCaptcha option standard. Read your vbulletin manual for details.

OKAY - well I just switched from standard image verification to reCAPTCHA. Let's see if that makes a difference.

I've been getting a moderate amount of SPAM - maybe one post a day or so, and we ban the user, ban the IP address, and report the details to
http://www.stopforumspam.com/add
to help others.

Another thing I just modified is that I made it so that even usergroups "Users Awaiting Email Confirmation" and "(COPPA) Users Awaiting Moderation" must "Require Human Verification on Configured Actions," not just "Unregistered / Not Logged In." Maybe this will help.

I also make users post 20 posts before they can post links. After installing reCaptcha i turned the protection off. Within an hour we had 40 posts of spam. I'm guessing the spammers are paying people in some third world country to manually spam.
