Administrative and Maintenance Tools - Multiple Account Detection & Prevention

It happens all of the time. Some members will make multiple accounts to back their own opinion or get an extra vote in a poll. Here's a modification that will detect and prevent multiple accounts, as well as notify the administration about multiple accounts. Inspiration for this modification came from the work of MPDev (creator of the Multiple Account Login Detector) and randominity (creator of the Multiple Account Registration Prevention). This is basically a combination of those two modifications but with new and improved functionality.

This is not an update to the "Multiple Account Login Detector (AE Detector)" nor is it an update to the "Multiple Account Registration Prevention." If you have either one of these (or both of them) installed, you should uninstall them before installing this modification.

With the initial release of Multiple Account Detection & Prevention, I believe that I have fixed previous bugs/complications as well as improved the efficiency and logic of the code. This is my first publicly released modification. I would appreciate any comments and suggestions!

Confirmed! This works perfectly on all vBulletin 3.6, 3.7, and 3.8 versions.

Unfortunately, I cannot give support right now. I may be able to help periodically, but until my schedule yields some more free time, I won't be much support. Please check back in a week or two.

How it Works
With every newly recognized login/registration, an account-counting cookie is set (or added onto) with the member's User ID. Depending on the settings, Multiple Account Detection & Prevention will analyze the cookie during login/registration to see if there are any multiple accounts.

Login Detection offers cookie-checking and reporting. Registration Prevention offers the same thing, plus more advanced features. First of all, when it prevents an account from registering, it actually moves the registrant to the Prevention Usergroup so that the administration can review the case. This also allows for customized privileges for recognized multiple registrants. Registration Prevention also has IP address detection which finds out just as much information about users. Depending on an administrator's preference, this modification can also reban a new registrant if one of their previous accounts has been banned. In fact, if the administration wishes, multiple registrants can simply be denied registration all together.

Whenever there is a detection/prevention, the modification will report the information to the administration through private messages, a new thread, or both (depending on settings). The Multiple Account Reporter can be any valid user.

Known Issues
- vB Optimise users: Reporting via thread seems to get messed up by vB Optimise, so try reporting via PM instead.
- PhotoPost vBGallery users: The registration handling appears to not work properly when PhotoPost vBGallery is enabled.

From what I can tell, these known clashes have been caused by the other modification's coding. The author of vB Optimise will not even work with me to fix it. Until they improve their coding, I'm not sure if I can do anything about these issues. As far as I know, administrators that do not use the above modifications will not have any problems.

Installation / Upgrade
Unzip the package (madp.zip), upload the files to your forum location, and import the product file (allow overwrite if upgrading). Please read the ReadMe.txt file that is packaged with the modification for more information.

Please remember to mark this modification as installed if you use it!
If you like it, nominate it for the Mod of the Month!

Thank you!

This work already on VB4. I've run on my board.

The ignored usergroup ID's are our admins and mods (5,6). The only think I've really changed is the name.

If the settings look good, how should I go about troubleshooting this?

Thanks for any input!

To answer my own question for the benefit of anyone who may run into the same issue, the problem was the plugin was set by default to send notifications as User ID #1, which does not exist on our forum. We changed the user ID to a valid user and everything started working as expected.

so this works perfectly even in vB4?
can someone confirm for 4.0.3?

kudos to the dev.

Argh. Uni hasn't been the best experience for me, but now that I'm out of school for the summer, hopefully I can pick this thing back up and see what I can do.

For all the people using, testing, and supporting this while I wasn't around to, thank you!

I'll try to make up for lost time, but please be patient.
