Okay! 1st of all I'd like to say I spent f***ing ages on this because the stuff confused my small mind. :( So I'm WELL proud of this. :D

What it is;

Well have you ever had people /part'ing your channel? /hop'ing your channel? Generally spamming your channel that way? Well with this you needn't worry about !kb'ing or trying to mode #chan +b nick etc. We all know how troublesome it can be to get the nick you need to ban, and with right clicking we can all make mistakes.

This is nearly fully customisable.

!sethop sets the amount of times a user can part a channel in 60 seconds.
!setban sets the amount of time the user will be banned for.

The rest is done automatically.

!sethop 0 turns off the protection. Any other number will set it.

!sethop 2
!setban 10

This will allow 2 parts per nick, on the 3rd it will ban, giving information on why s/he is banned. 10 seconds after the ban is placed, the ban will be removed. If anything is missing just say so and I will add it. (Y).

on *:TEXT:!sethop*:#: {
  if ($nick !isop #) && ($nick !ishop #) { notice $nick Only halfop's can set the hopping allowance for $chan $+ . }
  elseif ($nick isop #) || ($nick ishop #) && ($2 !isnum) { 
    notice $nick Please choose a number for the amount of timer a user can hop in 1 minute.
  }
  elseif ($nick isop #) || ($nick ishop #) && ($2 isnum) {
    if ($2 == 0) {
      set %hop.mode [ $+ [ $chan ] ] off
      msg $chan { Hop protection for $chan has been disabled. }
    }
    elseif ($2 > 0) {
      set %hop.mode [ $+ [ $chan ] ] on
      set %hop.allowance [ $+ [ $chan ] ] $2
      msg $chan { The hopping allowance for $chan has been set to $2 hop/s per user. }
    }
  }
  else { 
    notice $nick Unknown error. Please make sure you have followed the syntax; !sethop <number>. Remember you need to be a halfop or an op to use !sethop.
  }
