I downvote all Reddit-style memes, jokes, reference humor, catchphrases, and so on. It’s low-effort content that doesn’t fit the vibe of HN and actively makes the site worse for its intended purpose.

>Edit: WTF, someone downvoted "Enjoy the upvotes?" Pathetic.

You should read HN posting Guidelines if you want to understand why. Although I guess mostly in this case it is someone fat thumbed downvote.
