So the problem only occurs after you use “Hide Post”? That might be part of the problem, I suppose that deduplication only considers posts that are visible to you. Though I cant find the corressponding code right now to confirm it. Best if you open an issue in the lemmy repo.











Found it now, crosspost detection actually happens in the frontend. It only works if posts have the same url and are shown on the same page.
Opened an issue, but it will likely take a while to fix.
