Doesn’t change the voting situation. Since your votes need to be seen by other instances, Lemmy needs a mechanism for federating votes. Since instances are untrusted, there needs to be some way of preventing manipulation. Thus, AFAIK, Lemmy simply shares your votes across instances, letting each one tally them up. As a side effect, any server admin of an instance you can interact with can also get a list of all your votes.
