TLDR: 3 people working together can gatekeep content on the "active" and "hot" feeds on smaller servers/communities.
After some playing around, I noticed posts disappear after reaching a threshold. A quick search later and I'm in the Lemmy docs reading about how this all works.
In plain English, any three people working together (or one person with three accounts) can stop posts from appearing on the default feed. Once a post reaches -2 it will only appear to people who browse "new." Edit: Of course, it reappears after it climbs above -2, but it's a race against the clock.
As a smaller server, we're vulnerable to this. But we also have some extra mitigations - namely, @seahorse@midwest.social has to approve everyone who joins, and that might weed out bad actors.
So what can you do? Upvote content liberally, downvote sparingly.
Did they get rid of them, or did they hide it from the UI? Bots are the ultimate threat here, and they won't use the UI.
Both. Downvotes aren't taken into account for all beehaw posts and comments. Even if someone downvotes a beehaw post from another instance, it just won't send.
