We can see downvotes on kbin, not sure lemmy is the same.

Only from kbin, or possibly even just kbin.social (or whatever one’s local instance is). If you look closely, you’ll notice that every downvote you can see on kbin is from a kbin user, which is because kbin doesn’t federate downvotes from Lemmy.

If you lookam at OP’s Lemmy profile, you can see a moderate amount of consistent downvoting: lemmy.world/u/Call_Me_Maple?page=1&sort=New&a…
