Looking at various discussions, I'd say there's enough to attempt to steer narrations. In some cases users bury comments from such accounts rightfully with downvotes. But it's not just discussions - there are accounts submitting nothing but single-themed content to spread particular themes. My account isn't that much old but I was lurking around for years and I can say that quality of content and comments has significantly dropped in last 5 years. I'd guess it's because people running away from reddit settled here, because HN serves more generic stuff - with help of notorious spammers who surely get paid for uploading content from big media outlets every few hours.
