Is this a new problem?

There's always been low effort comments and content, here and all over the internet. A decade or so ago people used to write comments like "this" a lot to farm upvotes off another popular comment.

In comparison to other places this kind of thing is largely discouraged and unrewarded on HN, although I have noticed the quality of comments here has decreased over the years and low-effort comments are definitely upvoted more often these days.

I guess we all just need to be more proactive in downvoting them when we see them.
