I say leave them as is. It's good this way. Downvotes are healthy and should be used more often(https://hivel.ink/short/@rishi556/short-form-content-is-contnet). It's how content gets valued. I shouldn't be forced to justify why I think something should be valued one way or another.
The current reputation system is garbage and will probably be scraped if anything better can be made so anything to do with that can just be ignored IMO. It's not an accurate measure of anything. Just look at the current user with the highest rep.
Remember, none of the rewards are yours until they get paid out. Nothing can been taken from you with a downvote. You aren't owed the rewards that you see. The community is working for 7 days to put a value on your post. A upvote just means they see it as more valuable, and a downvote as less valuable. There's lots of posts I skip voting even though I think they are good just because I think they are at a good amount of value already(but can later change my mind and vote one way or another depending on where it is).
So sunsetjesus account is a real person going around and down voting in a willy-nilly way a lot of people and not a bot down vote account?
It's a bot probably looking at its actions(can't say for sure though, there's some weird people out there). But it's not interacting with any particular UI, but directly with the chain. It's using code to downvote somehow, probably posts that match its requirements.
