Not all of them are easy fixes. The following strings have multiple numbers and would be a candidate for Message Format:
js.flagging.delete_confirmjs.too_few_topics_and_posts_noticejs.too_few_topics_noticejs.too_few_posts_noticeadmin_js.admin.user.delete_all_posts_confirm
I’m not sure if the following are still used. Looks like they were removed with the topic list refactor a few versions back…
js.posts_longjs.likes_longjs.views_long
