I’ve occasionally noticed ordinary comments with zero upvotes to them. Yet, our own comments are upvoted automatically whenever we make them. So for comments to have zero upvotes, either something I don’t know about is happening, or there are people who downvote their own contributions.
I can’t help but wonder, why? It seems like extra effort without a clear reason.
My suspicions are that the post with no votes are not from other Lemmy instances, but rather from other federated platforms.
Mbin defaults to 0 by default, have to upvote manually.
