100%. Content sorting is (to my understanding) handled by peer vote rather than any kind of central algorithm on Lemmy by default, so a vote is much less about agreement/disagreement, and much more about doing your part in the process of separating the wheat from the chaff imo.

In my view, even a (non-bot) lurker who only views/votes is still contributing to the community, because they still add another data point for sorting. It’s a collective effort that generates a collective content algorithm, so a person should vote accordingly.
