Exactly... the system detected the log in of two different users (not related to each other) using multiple accounts

But the thing is that it did not prevented them to open two accounts, sending the new account to the dupe acc group.

In other words, the detection part, is working, but I cant make the prevention part to work.

I don't believe that this is the case, but I can test it for you. Please give me your forum's web address.

will this work with 3.6?

Yes, it should work just fine with vBulletin 3.6 and 3.7 and 3.8 installations.

Excellent mod. It would probably take me a day or to fully figure out what all the option so so can I get a little summary of what it does for what i need.

Lets say, there is a user who is banned but then gets another IP address and tries to register a new account, will this mod be able to stop him?

Yes,
work fine with vBulletin 3.8.1

thank you

For some reason the server load went from a measly 0.88 to 2.52 while the mod was enabled. Does to do any scans or anything?

Is it checking IP's?

Since the primary method of tracking is through cookie, the person will still be caught if they use the same browser and don't touch their cookies. The IP address checks are meant for a backup (in case a user clears their cookies). Some cases cannot be helped, but with the cookie and IP address checks, most of them people will be caught (even if they don't think that they will be).

Awesome :)

If you have a high volume of registrations each day, and you have IP address checks enabled, this could definitely raise the average server load. Also, enabling verbose mode for the reports will also raise the server load.

Last but not least, reporting through thread uses more queries than reporting through PM, so you might want to switch to the PM method and drop the thread reporting.

Gracias :)

Well the Plug in its working.
And I really want to thank you for all your help.
