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!

Hi Kiros, i installed your mod and tested it.
It detected double accounts, but i'm getting error when new members registering in my forum.

Fatal error: Call to undefined function: stripos() in /home/content/b/1/n/b1n/html/forums/madp/prevention.php on line 94

Any idea why i'm getting this error?

Open your AdminCP, go to the Multiple Account Detection & Prevention Options, and click on the question marks (help topics) if you want specific information on the options.

Thanks that explained things . I did not click on the ? marks ..

could it be possible to get when the re-ban happens , a post is made in a forum .. Like how the Report by New Thread is done for the multiple account detection ?

thnaks again ..

Oh dear. I'm sorry. I wasn't thinking when I put stripos() in there. It's only available in PHP5 and up. You probably have PHP4. I'll swap it out with strpos() in the next version.

Edit:

Actually, I might go ahead and make a PHP4 version. Stay tuned. Until I release it, please keep that problematic option disabled. I'm sorry about the inconvenience =/

As I've already said, whenever a multiple registrant is rebanned, it says so within the post. As long as you have Registration Prevention enabled, have correct settings for the Report by New Thread, and have the reban settings correct, it will say it within the post.

I have no clue what you said
Sorry.

Attention: Everyone... The next version (1.0.4) will be released soon, but I am in the middle of moving a website - the same website I develop the modification on. As soon as the site is reopened and the DNS is propagated, I'll be able to release the new version. Please be patient... It might be another couple of days.

Installed!!!
and Nominated!

[Kiros72]

Thanks, I love you too

By the way, I've decided to skip a small improvement and go for a rather decent set of improvements. So version 1.0.4 will not be released. Instead, version 1.1.0 will be

I may be ready to release it by later tomorrow night or the day after. Stay tuned.

I really need help. I keep getting spammed and most of it is coming from the same people. I can tell by the same and similar ads. etc. It's gotten way out of hand and it's killing my site.

I've honestly just thought about deleting the forum and letting the spammers win but before I do I thought I'd ask for help.

I tried installing this upgrade in hopes to finally permanately get rid of the returning scum bags that keep hammering my forum with spam.

I'm a complete rookie to installing new products and am having some trouble. I can't get into the "setting group" panel shown in the thread here. Could somebody please give directions to or help a total rookie find the answer to this problem? I feel stupid asking but I really need help.

I have uploaded the file :madp to my forums folder

Then I went to my admincp and imported the product at:
Plugins & Products > Manage Products

It seemed to instal ok but I can't figure out how to get to the settings panel.

OK, I figured it out.

Sorry to bother everybody with my ignorance.

Alright sir, i will wait for your update

[reptiliciuos]

mmm, think i am missing something here.

Installed fine, real easy product, but when active and testing, all new registrations ger the same error:

Fatal error: Call to undefined function: stripos() in /mounted-storage/home21b/sub001/sc20647-EJMW/******.com/madp/prevention.php on line 139

any ideas ??
