By advantage I mean posts from those instances receiving more visibility than others on feeds that sort by score (active, hot, top).

There seems to be at least two ways in which posts from instances that don’t allow downvotes receive an advantage:

  • They don’t federate downvotes. That means other instances only count downvotes from their own users but not from the rest of the fediverse.
  • A downvote sometimes can be counted and federated as an upvote. This happens when you first upvote a post and then change it to a downvote.

Let’s see an example. Suppose we are a user from instance A that allows downvotes and we want to vote a post on instance B that doesn’t allow downvotes. Watch what happens on instance C that also allows downvotes.

  1. Before the vote this is what users from each instance see (upvote - downvote = total score)
    A: 10 - 0 = 10
    B: 10 - 0 = 10
    C: 10 - 0 = 10

  2. Now we upvote the post:
    A: 11 - 0 = 11
    B: 11 - 0 = 11
    C: 11 - 0 = 11

  3. We misclicked, we meant to downvote the post:
    A: 10 - 1 = 9
    B: 11 - 0 = 11
    C: 11 - 0 = 11

If the post was hosted on an instance that allowed downvotes users from instance C would see a total score of 9.

    Keep in mind that not everyone is using the upvotes weighting, so it’s not just about “those who allow downvotes and those who don’t”.

    Personally, I find the whole upvoting/downvoting thing to be a very toxic feature that encourages hive mind and blaming divergence, so I hide scores and I sort posts and comments by chronological order. I would not use Lemmy if I was forced to be under the influence of social scoring, so defederating from instances which do not apply the same rules on downvoting would feel very detrimental to me.

    Upvotes/downvotes were implemented by websites like Reddit as a scaling trick, so they can get millions of users without the need to hire hundreds of thousands of moderators. But it turned out that adding subreddits with volunteer moderators worked better anyway, and this is already what we have on Lemmy, with instance owners and community moderators, so there is really no need for some dystopian scoring of everything someone says.
