I’m on KDE X11, where I configured a shortcut to input the license:

paste_license.sh

#!/usr/bin/env bash
sleep 0.5
xte "str ::: spoiler Anti Commercial AI thingy"
xte "key Return"
xte "str [CC BY-NC-SA 4.0](https://creativecommons.org/licenses/by-nc-sa/4.0/)"
xte "key Return"
xte "str :::"

On windows probably autohotkey would do a similar job. No idea about macs…
