If some things get downvoted way out of proportion, and those downvotes come mostly from people in certain instances, and instances have the power to block each other, it stands to reason some instance out there managed to block the instances that contribute the most downvotes, causing them to have mainly upvotes. Right?
A thing I learned on that other site starting with a R is that Up/Down votes aren’t rational you can get a lot of votes for a one line joke not answering the question, and get downvoted for a long argumented paragraph without anybody telling you wha’t s wrong. So I tend to not care about votes.
Indeed, I don’t get why upvotes are public, but downvotes are hidden unless you have some admin rights on an instance.
