Lemmy’s design is focused on quality content by ditching the Karma farmers and addicts. No more chasing upvotes—people here actually focus on real value instead of feeding the ego.
EDIT: I know there are upvotes and downvotes, but the problem with Reddit is you can’t post in most communities if your karma or reputation is bad. This is a big problem because herd mentality prevails there and if ypu have unpopular opinions you’re basically censored.
Lemmy isn’t designed to milk ypur dopamine with notifications every 10 upvotes, so you focus more on posting valuable cont instead of farming for approval and upvotes.
It’s one of two things
Your app doesn’t hide things that are marked as read. This is typically a setting you can choose.
The same content is being posted to multiple communities or multiple instances (if you are watching global feed). This is not something that can be fixed I think.
I have the same issue
Sometimes it’s the multiple posting, sometimes it’s just old posts that are still active and getting comments. Like 2 day old posts. Since they get so many comments still it’s likely that lots of other people are seeing them too
