Back in my days on Reddit, my favourite feature was the ability to hide individual posts if I had downvoted them. It made it easy to hide things which I didn't want to see or felt shouldn't be seen
i believe the general attitude on the threadiverse is that down votes are not a great option: they should represent low quality or untruth rather than simply dislike. given this preference, and downvote to hide might overload the downvote function: no longer is it a last resort, but it’s a normal part of browsing your feed. i’ve seen nothing but staunch opposition to overusing h the down vote feature in this manner
FYI, if you go to "Account Settings" and uncheck "Show Read Posts", this should automatically hide all posts that you open, up vote, or down vote.
I understand and agree though that having the ability to split that into separate options would be nice. But this might help you until they possibly add that option later. This is also tied to your account and not just the app, which is nice if you use Lemmy from multiple devices.
Currently though, I and several others are having issues where the last update appears to have broken that feature. I'm not sure if the issue is instance specific, (lemm.ee) or more broad.
I don't quite see the point of this — unless you refresh Lemmy homepage very often, you should see a new set of posts each time you visit regardless. Hiding the downvoted posts would only work when going to a particular community
I use lemmy generally once a day, and still see old posts I've voted on. It's gotten to the point where I have to block whole users just to stop seeing some of the hideousness that gets posted usually on ai coms, but sometimes /funny too). I'm very much in favor of the feature.
