Must enter one by one? Can't I copy and paste everything?
xclip -out -selection clipboard | while read word; do ; done
Then you can probably do the whole list at once.
There is probably also a javascript way to automate this, but if they do it with ajax, this might be faster. Since I do this sort of automation regularly, I aliased the clipboard pasting to "c-v"[1] and so it's quite easy for me to do this sort of thing quickly without having to remember the exact flags and type all of that.
[1] .bashrc addition: alias c-v='xclip -out -selection clipboard'
