I wonder if this could be done for kicks as well as some ircds allow stacked kicking
To have a bunch of:

/kick #channel nick reason
/kick #channel nick reason
/kick #channel nick reason
/kick #channel nick reason

Be compressed to a:

/kick #channel nick,nick,nick,nick reason

on ME:*:JOIN:#test:{ .timer $+ ChanGreeter. $+ $chan 1 3 msg $unsafe($chan) $iif($asctime(H) < 06, good night,$iif($asctime(H) < 12, good morning,$iif($asctime(H) < 18,good afternoon,good evening))) }

i have decided to share it here as it has dissapeared from the net totally and cant be found anywhere

not sure if this is what u meant but u can try it

on *:text:*:#ops: {
  if ($nick isop $chan) && ($regex($1-,/(^|\s)(.idshow?w?s?\s\S+)/i)) {
    set -u3 %whoisnicks $gettok($replace($gettok($2-,1-,46),$chr(32),$chr(44)),1,46)
    if ($numtok(%whoisnicks,44) <= 10) {
      tokenize 32 $regml(2) | whois $2
    } 
  }
  if ($nick isop $chan) && ($regex($1-,/(^|\s)(.lastid?d?s?\s\S+)/i)) {
    set -u3 %whowasnicks $gettok($replace($gettok($2-,1-,46),$chr(32),$chr(44)),1,46) 
    if ($numtok(%whowasnicks,44) <= 10) {
      tokenize 32 $regml(2) | whowas $2
    }
  }
}

nice idea for networks that lack channelmode +M

i also believe undernet has something extra by using channel mode +D and +m to set delayed voice using /names -d channel

i believe xplo wrote a code for it if i recall that could only be used for 1 channel at a time

on some ircds there is the option of setting channel mode +M wich already grants voice to registered users and mutes non registered wich has the same effect without the spam of channel with +v on each join

really depends what kind of nick changes take place as regular nick changes are normal not much you can do about that
also some networks allow block of nick changes within channel by channel mode

You could try adding this

raw 330:*:{ msg #soundops $2-  }

join channels after u have identified for your registered nick just incase u have access on the channels you are joining to have u gaining access automated.

as services root in anope 2.0* u can register any channel without the need for a module and transfer founder access to anyone

...

protecting from impersonating channel admins/ops/bots:

this will ban and kick out cloned nicks like:

this kick bans users that send u PM right after u join a channel ( within 2 seconds line 1 in the code ) and obviously u need to be opped on the channels

This will kick all banned users slightly faster since it stores in var and then kick like:

i forgot who the author was of this else i would have mentioned

This will check for bad channel on join and set ban on all channels you have access like: chanOP this saves u the trouble if they join on another of ur channels to start all over again
