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.

How would you set it so that it auto bans the new account if the old account has already been banned by mods?

Thank you! :banana:

Great plugin.. thanks..

Do you ever plan to expand on it?

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 agree... i have legitimate multiple users who share a computer and am getting multiple flags. i actually thought this was a feature in one of the earlier revisions - i could be thinking of something else though.

You can ignore specific userid's that you don't want to have report to you.

I agree! Seems to be catching many users inside their own networks.

Oh I know, I just want him to add an option to automate that process

[Pathor]

Works fine!

Click install!

It shouldn't report the same users more than once unless:

a) the user logs into an additional account not already logged,
b) the user has somehow reset their cookies and started over (some security concious people will use a program to clean up their internet activity)

I don't have an autoban feature planned; but it wouldn't be hard to add it I wouldn't think.

[Majidm]

It must be the cookies then... If you could make an option so that it only files 1 report per User, that would be great.
