Because currently, it seems like the only thing it’s recording are downvotes. Meanwhile upvotes are completely ignored, leading to pretty much every profile I see having a negative reputation.
Also, I have a very fragile ego and my -6 reputation hurts a bit.
Without downvotes, you end up with Twitter-tier garbage discourse and arguments because there’s no way for the community to vote to remove an idiot’s platform, just clap-backs and ratios.
The up/downvote system is far from perfect, but I’d really rather not lose it as the fediverse draws more people in. I would much rather have my opinion hidden on occasion because I pissed off a wasp hive than have the content I consume be filled with toxic bait that can only be hidden if a moderator gets involved.
