duplicate ip/password list!

and here it is, finally.. perhaps one of the sweetest hacks i've ever installed.. unfortunately i didn't write it, but wired from http://www.xirgo.com (an awesome host, btw) did, and he gave me permission to release it on here.

this is the duplicate ip/password list hack. this basically shows all duplicate accounts on your vb forum sorted by their ip and/or password. this easily allows you to detect who's really who on your forum, and delete/ban accounts that you think are duplicates.

basically it works like this. there are two parts to this list, one part sorted by duplicate ip, the other part sorted by duplicate password. you can definitely tell users have multiple accounts on your forum if you see two (or more) users both with duplicate ip's AND passwords. this list also lists their post counts and their last visit date, so, if you want to just delete one of someone's duplicate accounts, you can choose to do so by either their last visit date (delete/ban the account that hasn't been on the forum longer), or by their number of posts (delete/ban the account that has the less posts).

please note that NOT ALL duplicate pw's are duplicate accounts, obviously. any user can happen to have the same pw as someone else. i wouldn't recommend deleting people with JUST duplicate pw's, nor with JUST duplicate ip's, because of shared accounts on the same connection, etc., but they can definitely be fishy.

to install this hack, simply put the dupeip.php file into your /admin directory of your vb forum. then to access it, go to yoursite.com/forum/admin/dupeip.php, of course.. that's it! no templates to install, no files to modify!

NOTE: the passwords on the list are in their VB encrypted form, but to be safe, only show this list to the other admins of your forum, although by putting it in your /admin folder it will ask for an admin login anyway.

this is what I posted:

I think on my board that hunting for similar sounding names would not prove
fruitful at all.
I suppose it all greatly depends on how many users you have as to the
intensity of an opperation like this. My php & SQL knowledge ends at this
level!

I would much rather concentrate on a script that would use the IPs in the
posts table and look for users using the same IP within a certain time
frame, eg 15 mins. This should catch people out when they change login from
their real name to the false name in order to flame someone.
Obviously doing a search like that on the post table would be a
server-destroying style query, so my plan would be to feed it a user name
that was suspicious. It would then crank back through the last 20 posts of
that user, grab the IPs, then see if anyone had used that IP within 15 mins
of that post time.

Does that make sense? Do you think it would work?

I just wanted to say this is a LIFESAVER for the board I run. Great, great add-on. This should be in vB3.

Hey, would anyone be able to modify this hack so the passwords aren't encrypted? It would be a lot of help!

Thanks

This is imposible. You cannot de-crypt the MD5 hash.

You can add more features to this by adding the user's usercp options. Like sigs off, or how many posts per page they are viewing.

Anyone know how to combine the two and view by BOTH duplicate IP's and passwords? Yes, I am this lazy, and I have a lot of duplicate IPs and duplicate passwords on my forum, and finding the ones that have both in common is becoming tedious. Any help?
