Hey buddy, it's terribly inconvenient to just... keep scrolling past images we've already seen. I mean yeah, we could just downvote and move on. Or even click the 'hide' button. And yeah, it might take less than a half of a second to see the image, recognize it, and move on. But that's a half second I'll never get back. That's an eighteenth of a scroll wheel rotation. That'll decrease the life of my mouse by a few seconds. If you weren't on reddit for the 4-8 hours it was visible on the front page of this subreddit, that's your loss buddy.

So instead of moving on, the logical thing to do is to click the link, let the comments load, then rant about how terribly annoying scrolling past links I've already seen is, especially considering how infrequent reposts are. I mean, reposts? On Reddit? It's so rare I should probably rant about it every single time it happens. Just remember that next time you want to inconvenience me for your own sake. And you don't forget it.

/sarcasm.
