Who might this New User be?

Hiyas,

When a new user registers your board, this hack analyzes his email, password, ip address and isp (ranged ip) against existing board members and produces a sorted list with probabilities about who this new user might be. (See screenshot below). This list will be emailed to you with new user notification mail. (The probabilities can be modified by you so it's you who decide how matched results are sorted and ranked, dont blame me!)

Tested and will work better in relatively smaller boards (less than 3000 members). If you have a small board, this hack may help you a bit to track and pinpoint existing users if they re-register with different usernames. For large boards, IMO it's pointless to track new users anyway..

As far as I know it will work with ANY vbulletin version so feel free to try. Installation is very easy, actually 2 simple steps and will take you 2 minutes to apply..

If they change their both ip, isp, password and email, the hack cant get them, yeah I know! This is the best we can do with computer technologies. If you have higher expectations and demands, you may regard consulting a "Seer"..

If you liked this hack, I suggest checking Jawelin's nice Paranoid dupe user buster when moderating Hack too. They make a good couple and I use them both.

Click Install button, if you installed the hack, thank you!

Enjoy! \=^))

Great hack, i will install this one later. Thanks.

Very nice idea and implementation.

Many thanks even for such undue greets....
I'll use ASAP.

Just a question: I have enabled moderation, but not email notification to the admin. I would, if some percentage value is overcome, receive that email.
Which variable should I check ? Do you think it should possible ?

I mean, if my $newuseremail is usually empty, i could put at the end of your hack something like:

PHP Code:

    if ($i>1)
      $newuseremail=$webmasteremail; 


By now I use the counter of matches, but actually don't like it...


Thanks again.
Bye

awsome stuff!

note about installing on 2.0.3: i put the code on register.php just before this

$DB_site->query("INSERT INTO user (userid,username,password,email,".$newstylefield......

@Jawelin: To add such a feature, first find the part in the hack code:

PHP Code:

$sorted_matches_pro[$i]=${$result}[probability].".".${$result}[userid]; 


After that add:

PHP Code:

if (${$result}[probability]>X) {$alert_tick=1;} 


Replace X with your probability you want to check.

Now if a user's possibility of being another user is more than X%, then hack will flag the variable $alert_tick and by checking it in register.php, you can make the script send you email notification.
Like in your code:

PHP Code:

if ($alert_tick==1) {$newuseremail='youremail@domain.com';} 


Hope that helps..

@All: You may ignore this message if you dont want to have a feature like Jawelin asked.
