I put the english text into Google translate and copy the translation into the notice. I do that with notices that may be of interest for the admin of gnusocial.jp. (Or when I directly address him.)
Sadly, lists don't work in gnusocial right now (or any longer).
I put two accounts into a list which I subscribe to as well. One subscriptions doesn't feed into my Home Timeline, the other does. But both don't feed into the list timeline.
