On Hexbear, moderators may factor upvote activity into moderation decisions.
Some users treat upvotes as a “mark as read” function, which weakens score reliability and therefore negatively impacts The Algorithm.
Please provide a separate mechanism for users to identify posts that they have already read, which will persist on later visits.
The API has an endpoint for marking posts as read. It would be a matter of adding a button to the interface to mark the post as read.
I'm sure if an issue was opened on the Lemmy UI side it could be implemented by someone.
