I would highly recommend consulting the moderators of that community. The modlog, which is public, but which I will assume you don't know how to access however you access Lemmy, shows that automoderator removed the post, a mod approved it, and then quickly removed it. In both cases, unspecified rules were said to be broken.
I don't see a problem with it personally, but I am not a moderator there, which is, again, who you need to consult.
