Isn’t that supposed to only happen on Posts>All>New? Shouldn’t Active/Hot posts require some existing engagement before appearing?
Does lemm.ee sometimes sync with federated instances, which is when new content floods en masse?
This is one of the experiences I’ve had that makes Lemmy feel far more janky than reddit.com/r/all
Looks like @sunaurus@lemm.ee (who admins this instance) is holding off on updating the server to 0.18 because of bugs and is likely waiting until at least a 0.18.1 update to upgrade lemm.ee (see this post)
