here's the proper anti-modlet script. It can turn encrypt all your messages into chinese.
https://hastebin.com/raw/osuluxojumcommands are /enc to turn on encryption for the current room. /dec to turn off encryption. /img to post an image
you can do "/autodump (absurdly long wall of text)" and it will spam for you without triggering showdown's flood protection
and /stopdump to stop the dump
finally, /roomvoice all to voice everyone in the room (if you're champ obviously)
if you set it up right you'll be able to see glorious sekret mesages and imageposting. if you didn't, you just see moonrunes.
plug it into tampermonkey or greasemonkey depending on your sexual orientation
