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
ive got no idea, i just noticed its all from the same community regardless of age whenever it happens
