Since a lot of people request these two flood protections in the forum. I figured they should be posted. Might already be in here somewhere a few pages back but, oh well.

on *:start: { 
  ;if user sends more than %flood.lines in this time ban them 
  set %flood.unset 3
  ;if a user sends more than this many lines/actions in %flood.unset ban them 
  set %flood.lines 5 
  ;this is the bantime in seconds 
  set %flood.bantime 600
} 
ON @*:TEXT:*:#: { 
  if ($nick !isop $chan) { 
    inc $($+(-u,%flood.unset)) $+(%,flood.,$chan,.,text.,$nick) 
    if ($($+(%,flood.,$chan,.,text.,$nick),2) >= %flood.lines) { 
      ban $($+(-ku,%flood.bantime)) $chan $nick 3 Don't flood 
    } 
  } 
} 
ON @*:ACTION:*:#: { 
  if ($nick !isop $chan) { 
    inc $($+(-u,%flood.unset)) $+(%,flood.,$chan,.,action.,$nick) 
    if ($($+(%,flood.,$chan,.,action.,$nick),2) >= %flood.lines) { 
      ban $($+(-ku,%flood.bantime)) $chan $nick 3 Don't flood 
    } 
  } 
}
