I sort by active and this is how my feed looks. Except I see the duplicates every 5-6 posts. But I see the same ~10 posts for maybe 100+ with a few non-duplicates sprinkled in. Same with sorting by hot.

And then 24h later, it's the same feed, with the same duplicates.

36h later and still maybe 1/2 are the same duplicates from 2 days prior.

It's pretty bad, finding threads I'm interested in keeps getting harder and harder.
