Master-Of-Death,
That's not really the correct way to create
an identifier. You simply made a command and
stuck a '$' on the front of it. Typically an
identifier returns a result as does $me.

alias add .auser -a blist $address($1,2)
alias del .ruser $address($1,2)
on @blist:JOIN:#:ban -k # $nick 2 Pwned By $me
