well a simple script could change it to lowercase. Something maybe like

alias lowercase {
if ($script($1)) {
echo -a Coverting file $1 from uppercase to lowercase
set -u %file.tmp $+($1,LowerCase,.txt)
write -c %file.tmp
filter -fk $1 convert
echo -a Coverted file made to text file %file.tmp and placed in mIRC directory
}
else echo -a Error: file $1 not found
}
alias -l convert { write %file.tmp $lower($1) }

usage /lowercase file ie lowercase drclone

But i highly doubt that the reason is to stop rippers
