What was the actual article?because linking a deleted post takes you to an error page.

300 upVotes and still a "moderator" kill it, this is sad. if it breaks one's community's rules, the post should be mooved to an other community instead ... unfortunately, Lemmy's tools do not make it possible at the moment.

Sad for users and for you.

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.
