Multiple account login detector (AE Detector)
 

If you are like me and migrated from .threads, a common modification was an "AE detector", a simple mod that saved a cookie of a history of ids logged into on your site. If someone logged into more than one account, you got a PM letting you know that your site was being accessed from multiple accounts.

Over the years this was very helpful in identifying users who were posting under multiple accounts (alter-egos!) and users who would return after being banned.

You might be wondering why I don't use the vbcookie call - well, thats because on logout all vB cookies are cleared, so we need to store a cookie that is not effected by the login/logout process.

New Installation
1. Add New Product with attached XML
2. Go to vBulletin Options -> AE Multiple Login Detection Settings and set your specific settings.

Time to install: Easy - 2 minutes.

Upgrade
If you installed this as a Plug-in manually, you can delete that plugin and install this Product, just make sure to go into the Options and set them accordingly.

I hope you find this useful and will click INSTALL if you use it; should it prove useful to enough people I can look at making this installation more automated without the need for edits and an Admin Options page.

To upgrade you will want to reimport this XML file and edit your options accordingly.

1.0.3
-----
. Added a check to ensure that users weren't deleted when reporting violations
. added htmlspecialchars_uni call to username

Note: I am unable to get the call to construct_phrase with $vbphrase['multiplelogin_alert'] to work reliably, as such the $message variable is still set manually inside the plug-in and not via the phrase. If anyone has an idea of why this might not always work, I'm all ears.

1.0.2
-----
. Updated to include exclusion groups, users
. Changed so PM is sent by ae sender id

1.0.1
-----
. Released as a Product (thank you PHPGeek2k3 for your help)
. Added option to post to a forum versus send a PM (or both)
. All settings moved into Admin Option

1.0.0
-----
Initial release.

Text file, please? ;)

oo first install thanks...
Lets see what ive broken now :)

Cheers for this

Okay, text file attached with the change which makes the usernames clickable profiles (you'll need to modify the URL to the member.php).

I like this a lot. Thanks for your work so far on this. A couple things I'd like to see added though...

1. An option to enter particular user ID's by number that are NOT subject to the check.

2. An option to choose to receive the notices either by PM or e-mail. In our case, we'd prefer e-mail.

Wow thanks!

Userid of recipients, yes?

yes that is correct

Actually, it's usernames if I understand the vB system (I use the usernames). Userids would be nicer, but I believe the PM system is expecting usernames.

The admin variable is expecting a userid, though.

It would be nice to have the actual instructions from the first post in the text file also, sir. ;)
