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!

Is there a way to prevent it from detecting certain ISPs like AOL? AOL ISP are shared between many users.

I am concerned how it would work with AOL.

Yes, one of the features is "Ignored ISPs." AOL is ignored by default, but you can remove the domain from the exclusion if you wish. Also, this only works for IP address detection because it doesn't have to do with the cookie detection. If you don't use the IP address features, then you don't even have to worry about fiddling with the Ignored ISPs.

Hope that helps

The "user" you have set to post the thread can post in whatever board you wish for it to post in, right?

[cynthetiq]

yes, it's the user account 1 and used by the board owner. I'm going to try a different user account just in case.

Hey, I know that guy whom you mention in your quote ...

I would very much apprecciate, if this mod here would be integrated with a look up at zen.spamhaus.org to stop those spammers.

I'm sorry, but this isn't a spam detection system. The scope of this modification is all about multiple accounts. If you want to use a spam modification, it should still work just fine.

You have vBOptimise installed, don't you? Disable it and the reports should work. I've heard that reporting through PM still works while vBOptimise is enabled, so you might want to try that as an alternative. Sorry about the confusion.

But Thanks for help :up:
