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.

Yes, I'm having a problem with it reporting the same users everytime they log in.

I would also like to stop multiple reports of the same user.
Thanks

Would love to see this also

I not sure if i dare to update to the latest version as its working great?
Does it still say the usernames of who its detected in the latest version?

A nice feature would be to turn off multiple-reports from the same users... Although it has helped catch a lot of users, we do have some that just share their computer with their friends/siblings etc.. (we're able to tell because our site has freestyle battles with live audio recording, we can hear different voices etc..)

Cheers.

i would like to see some kind of way to prevent users from making another username if it picks up the cookie... this way you dont get a reminder cause they cant make another username..

Could this hack be used to detect account sharing?

I'm not sure what you mean - this is exactly what the mod does, reports when a single computer is used for multiple account accesses.

Still cannot get it to post in a forum
