Multiple accounts detector/Prevent multiple accounts registrations

Compatible XF 2.x versions

This app scans the database to detect members who have registered multiple accounts at your forum, and it will list the results. You can also prevent members from being able to register multiple accounts on your forum. You can find its settings under the Logs section at your Admin Panel->Multiple accounts detector. Only admins with the permissions to view Multiple accounts detector will be able to view the multiple accounts logs.

Detection Methods:

1) Registration method:

This method is based on scanning the xf_ip table for members who have registered more than one account at your forum from the same ip. The ip address in question will be displayed along with all members who shared that particular ip.

2) Ip login method:

This method is based on scanning xf_ip table for members who have logged in to different accounts from the same ip. The ip address in question will be displayed along with all users who shared that particular ip.

3) Device detection method a.k.a. the "Fingerprint tracking":

This is the most accurate method imho.The app adds a unique cookie to members devices when they browse your forum or log in to your forum. The same goes for all newly registered members after they first create an account. The cookie expiration date is set to one year and its unique string is associated with the members device and stored in the app's table. This means if someone logs in to your forum, logs out and then logs in using another account and a different ip address, then it can tell that it was the same person. It means that person has to use same machine, same browser irrespective of the ip address he/she is using. Please note that this method will take affect only after the app has been installed.

Prevent multiple registrations:

The app adds 2 settings to prevent the number of accounts that members can register at your forum based on their ip addresses and devices. Please note that this is valid only for members who will register at your forum after you have installed the app.

The ip addresses in the screenshots are blured out for privacy reasons.
