I saw that entry. It was in lemmy.world, not .ml, and given the target of the joke I don't think that the .ml team would care about it.

Yup, pretty much. They never communicate properly who is removing the content / banning the user, and why. And they clearly don't want to. (Perhaps the .ml admins are waiting for the devs to implement transparency features into Lemmy /s)
