When visiting this community from a stock Lemmy front end, there is down-voted spam and garbage near the top of the timeline. This happens regardless of the view selection (hot, active, scaled, etc). Certainly if the user asks for the “hot” view they should not be seeing negative scored threads near the top. And ironically, using the “controversial” view pushes the negative threads further down, which is the complete opposite of what’s expected.
Mbin fails to show the spam at all, even when selecting the “Newest” view, which we expect to show everything in chronological order regardless of score. So mbin is broken too.
The 3rd-party Lemmy client alexandrite behaves more like mbin, and does not show the spam even if a chronological order is requested.
My guess for what you’re seeing:
Not sure what’s happening with Alexandrite though. That might be a bug
Best you can do is report it and wait for mods/admins to see it
