Anti cloned nicks

By simo on Aug 02, 2017

this will ban and kick out cloned nicks like:

nick123
nick893
nick982
nick165
nick672
nick98387
nickjhe98

also it checks for cloned hosts/ips

use this code with the enforce ban code i posted to make it kick out clones faster:

i tested it and this is an example of its working

on *:JOIN:#: {
  if ($nick(#,$me,@&~%)) {  
    var %Clone.join.flood2 = $+(*!*@*.,$gettok($address($nick,2),-2,46),.,$gettok($address($nick,2),-1,46))  
    if (%clone-join. [ $+ [ # ] $+ . $+ [ %Clone.join.flood2 ] ] == $null) {
      set -u3 %clone-join. [ $+ [ # ] $+ . $+ [ %Clone.join.flood2 ] ] 1 
    }
    else { inc %clone-join. [ $+ [ # ] $+ . $+ [ %Clone.join.flood2 ] ] }
    if (%clone-join. [ $+ [ # ] $+ . $+ [ %Clone.join.flood2 ] ] >= 2) {
      if (%modechanx7 != $true) {
        .raw mode  $chan +b %Clone.join.flood2
        set -u3 %modechanx7 $true
      }
    }

    var %Clone.join.flood = $+(*!*@,$remove($gettok($address($nick,2),1-2,46),*!*@),.*)    
    if (%clone-join. [ $+ [ # ] $+ . $+ [ %Clone.join.flood ] ] == $null) {

    }
    else { inc %clone-join. [ $+ [ # ] $+ . $+ [ %Clone.join.flood ] ] }
    if (%clone-join. [ $+ [ # ] $+ . $+ [ %Clone.join.flood ] ] >= 2) {

        .raw mode  $chan +b %Clone.join.flood
        set -u3 %modechan1MR76567 $true
      }
    }

    var %join.flood.ident = $left($remove($gettok($address($nick,3),1,$asc(@)),*!*),4)
    if (%join. [ $+ [ # ] $+ . $+ [ %join.flood.ident ] ] == $null) {

        .raw mode  $chan +b $+(*!,$left($gettok($gettok($address($nick,5),1,64),2,33),5),*@*)    
        set -u3 %modechan1MR541 $true
      }
    }

    var %join.flood = $+($left($nick,4),*!*@*)
    if (%join. [ $+ [ # ] $+ . $+ [ %join.flood ] ] == $null) {
      set -u3 %join. [ $+ [ # ] $+ . $+ [ %join.flood ] ] 1 
    }

        set -u3 %modechan1MR $true
      }
    }

Nice idea and script. Have you allowed for things like netsplits (where services go down) and folks rejoin on mass to find they all change by default to a fixed "Default1234" nick ?

somehow hawkee wont allow changes to posts i wanted to update it but i get weird replies about adding code while code is there and already posted

but its a good thing to think about the netsplit scenario

It was more of an observation more than anything.. alot of clients dont use auto-id .. and on netsplits or if services go down.. its an all too familiar sight lol .. en-mass nick change to server default
