*** HUGE thanks to RusselB for adding the ban part in :)

*edit i made stoppers, if your hop or op it will halt :)

*this script is intended to cutdown on flooding in +m channels

Help:
inc -u7 $+(%,spam.,$nick) <-- -u7 7 stand for seconds
if $($+(%,spam.,$nick),2) == 5 { <-- 5 means lines
if $($+(%,spam.devoice.,$nick),2) == 5 { <-- 5 means times you will devoice someone before 10 minute ban

ex: the above will devoice the person if they say 5 lines in under or at 7 seconds

on @*:TEXT:*:#:{ 
  inc -u7 $+(%,spam.,$nick) 
  if $($+(%,spam.,$nick),2) == 5 { 
    .mode $chan -v $nick | msg $chan 4 $nick is spamming [devoice 15 sec] 
    .inc $+(%spam.devoice.,$nick) 
    if $($+(%,spam.devoice.,$nick),2) == 5 { 
      .ban -ku600 $chan $nick Banned for multiple spamming 
      unset $+(%,spam.devoice.,$nick) 
    } 
    else { 
      .timer 1 15 /mode $chan +v $nick 
      .timer 1 16 notice $nick  youve been revoiced, dont spam again. 
    } 
  } 
}
