Can someone provide a quick rundown on what makes them "problematic" to cause such a reaction?

To be fair, Cowbee didn't specify that they successfully tried it!

I don't know the context of this comment but it seems like they are only quoting the About section of toots.matapacos.dog (hexbear-like mastodon instance), so I don't think the title is 100% accurate even though I'm aware of lemmy.ml's shitty moderation.

"Managing editor Wyatt Reed, contributor Mohamed Elmaazi and regular freelancer Jeremy Loffredo worked for Russian state media before contributing to website."

"Grayzone staff Blumenthal and Aaron Maté acted as briefers on behalf of the Permanent Mission of the Russian Federation to the United Nations at UN meetings organized by Russia."

It would have been cool to involve the community by doing some kind of art contest. (Not saying I would participate, I just like the idea.)

It's because OP made two separate posts and therefore uploaded the image twice so lemmy doesn't recognize it as cross-post (check the image URLs, they are different). If OP properly cross-posted it, the URL would be the same and you wouldn't see it twice in your feed.

• Rate Your Music charts or lists

If you don't have a problem with sharing your listening data:

• Last.fm (for example, check "similar to" section of artist pages or "similar albums" of album pages)
• ListenBrainz, a free and open source alternative to Last.fm (for example, Music Neighbourhood, ListenBrainz Radio, or the "Created for you" playlists (they have been criticised by people for having too little variety, but according to the devs this will increase as more people use the service))

Or you can just ask people for recommendations.

It usually updates daily though. Check the burger menu at the top right. It shows you when the data was last updated. The README of the github page also says that "publish-pages" is failing, whatever that is.

We searched high and low, but we couldn’t find the page you're looking for. It may have been moved or deleted, or may never have existed at all.

I'm assuming this has something to do with the update to 19.4 that somehow messed up the Lemmy Crawler. awesome-lemmy-instances seems to have a similar problem.

I don't think @lodion@aussie.zone's information is correct because I remember seeing lemmy.ml in the instance filter list just a while ago.

Also: What does any of this have to do with the moderation of lemmy.ml? I also don't like their moderation but does that mean the instance and their communities shouldn't be visible on the Lemmy Explorer? Who should decide which instance should or should not be included on the list? If you want to avoid the instance like I do you can just use the filter to remove lemmy.ml communities on the community browser of the Lemmy Explorer.
