Version 2.1.2 - Fixed MySQLi bug - Introduced GOLD/Premium Version
Version 2.1 - Added BBCode to Banned Users and Post Count Options, better debug info
Version 2.0 - Added report for Registration (User) IP Address Checking

Check out the GOLD Version for these additional features:
  • Run reports directly from the Admin CP anytime you want
  • Post daily report as a "New Post" into an existing thread rather than a "New Thread" each night
  • Access to another Gold Mod- Recent Registration Check- will block spammers and scammers trying to register multiple accounts from the same IP address

This mod will run a nightly scan of your "post" and/or "user" table. It will report if it finds any users sharing the same IP address. You choose in the options how many days back you want to look. (Max of 5000 days, but please use more reasonable limits.)

If any "duplicate use" is found the IP addresses, usernames and optionally the posts themselves will be reported.

See a real report: Report Demo at Qapla.com

The report takes the form of a new thread posted to the forum of the Admin's choosing (A private forum for mods or admins is strongly recommended.)

There are options for whitelisting (ignoring) specific IP Addresses and/or userids so if you or your mods post as other users you can prevent that from being reported. If you use the Zoints Anonymous Posting mod you will want to put that userid on the whitelist else the report will out whoever posted "Anonymously."

NOTE: There are PERFECTLY valid reasons 2 or more users may share the same IP address. This report in and of itself is not proof of malicious activity. Users that connect by mobile devices, work in same offices, or go to the same schools for example would likely share the same IP address on some posts. So would too any users connecting from the same home or public Wi-Fi network.

As of version 2.0 there is a report for both the "post" and "user" table. The "user" table will find when 2 or more users register with the same IP address.

Tested and working on VB 3.8.7 and VB 4.1.12/4.2.0 and should work on all 3.7 / 3.8 / 4.x versions.


Please "Mark as Installed" if you use this. :)
Donations always appreciated. :up:
Nominate MOTM if you LOVE it! ;)

Very nice, been waiting for something like this, any chance of making it check the user table too for the registration IPs?

Thanks :)

I suppose checking the user table would be possible where it could report duplicates but it's not dynamic like the posts table. Once two users register with the same IP they would always show up in the report. I suppose I could limit the report to maybe the last x number days of registrations but it should be longer than the post check.

I will think this through a little better and figure out if it is practical to include a registration ip check based on feedback I get from the current version. :up:

Version 2.0 Released- Now will check the User table too (For Registration IP Check.)

The first time I ran this report I saw one IP being used by 18 people I hadn't noticed. They had never made a post but when I checked their profile they had all spammed their own visitor messages with links.

Without this mod no telling how long they may have lasted.

You will need to do a full install - that is upload the new php file AND import the product xml file, overwriting each, if upgrading.

Excellent addition. V2.0 found a spammer with 4 user id's on my forum that the first version didn't detect. Thanks BOP. If they spam via PM and never post this will find 'em.

That one is for vB Version: 3.7.1
Some say it works on vB 4 some say it doesn't.
That one isn't supported, this one is, by a Moderator of vB org as well.

I actually use another old version for such as this, and it works fine, but in the future I will start to use this one
