Weird. I looked into lemmy.world mod log and filtered for them: the latest action shown to me was 4 days ago ... maybe a bug in the filter mechanism? Also, the post from yesterday is still visible to me on unilem.org. That seems to be a federation issue though, with posts not reliably getting removed on federated instances. If I look at linuxmemes via lemmy.world, the post is indeed gone. I saw in the mod's profile, that they posted something concerning moderation, but trying to view that only threw an error for me. The overall lemmy experience seems to be still quite buggy.

TL;DR: You are right and the mod is still active. For a slew of reasons/bugs it looked otherwise to me. But I should have looked more closely.

Anyways, I've written to them and linked to this post.

Edit:

I just checked again, to see if I made some stupid mistake. This is the filtered mod log:

And I still see the new post (and the old) which you said was removed:

If I didn't know better by now, I'd still say that linuxmemes looks unmoderated (at least on my end).

Thanks, I'm not sure how democratic that process is, though ;-)
