I do not think is a good idea to use it

timerxaway $+ $network 0 10 /raw -q who *

on a lot of people will have server problems and anyway you do not need to know that those who are on shows or you are so /who $chan would be better

Error, /who limit of 50 exceeded. Please narrow your search down and try again
at this alias

alias nickaway {
  cnick -a $1 4
  HALTDEF
}

you're not sure this feature is enabled in abook
why not use
/cline [c] <@nom>

we flood you with this

echo -t $active 14 $+ $6 is away.

uses a addtok and does everything correctly on a line

together with your raw event

raw *:*:{
if $numeric == 352 {
...
}
elseif ...
 }

alias in your back you do not even checked that you are away if you're not, you will become so used away $away
we join in thy Who uses $ chan
on me:*:JOIN:#:who $chan

I have not watched the rest of the code attentively
