Translations from Danbooru are often used elsewhere and I haven’t heard that it bothered anyone as long as proper credit was given.
Look at the posts’ note histories to find out who the main translators were. If you don’t want to check all posts, at least check a few across the series/chapter because sometimes a different translator takes over after al while. You don’t need to give individual credit to all the users who only made small changes or translated only a few bubbles.
I’ve seen several scanlators credit us like “[name] and the Danbooru fairies”.
