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.

Hi,
Thanks very much for this useful plugin.

May I suggest something ?
What if we could get some more informations like :

- what new username is used by the user
- what IP was used by the user before and after (if different)

Thanks anyway

Great hack, already caught a few Can anyone comment on how many queries this causes on the forums? Does it increase server load much on a large forum?

My load has gone up, but I've changed a few things, mods etc... just trying to figure out what may be causing the load increase, whether it is this or something else.

Thanks

unless you probably have multiple people constantly logging in all day long as in serveral a second then this should not be a problem with your load. more and likely something else

Thanks

My mistake, I didn't import it under Products. Silly me! Works wonderfully now.

Thanks!

If I may suggest one thing: I would love to change the phrase which is posted on every multiple login. But I can't since it is not in the phrases. Would love to see this possibility

May I ask why I cannot seem to download the attachment? Instead it is just coming up in my browser as text...

Actually, this mod has no queries associated with it. It's strictly cookie based.

If I may suggest one thing: I would love to change the phrase which is posted on every multiple login.

The next update will do this, for now you can edit the text in the plugin.

You should click Save As... to save the XML file to your computer - once saved as a file you can upload it to your Admin CP.
