This article will show you how to check the activity of an IP address in phpFox. This is a good way to check to see which members are logging in on multiple accounts, and finding which IP addresses are from spam accounts.
Login to your admincp and select Tools > General > IP Address
Type in the IP address that you want to check and click Search.
You should now see a list of activity from that IP address, including the user name of the member logging in with that IP, and when they logged in.
You should now be able to monitor your site’s member’s activity by checking their IP address activity.
