At first I thought this person would only downvote short comments that have little content beyond saying that the user took the survey, but I’ve since noticed that even “I took the survey” comments with very detailed critiques are getting the single downvotes. My guess is this person doesn’t like the idea of some people getting 100% positive ratings through posting only survey comments, as survey comments would be the easiest way to attain that otherwise, or thinks that the amount of karma awarded by other users for these comments (even the detailed ones) is too much, and that karma should mainly be reserved for quality discussions.
Personally I think the amount of karma awarded for the short and simple survey comments should be based on the difficulty, time commitment, and benefit from having people take these surveys, but I think the amount of karma being awarded already is in line with that. Sure, there might be a few people lying by saying they took the survey when they in fact didn’t, but I suspect that’s pretty rare. I would like it though if there were some users who prioritized quality in deciding whether to upvote comments, so that it would be easier for people to quickly locate the most useful comments when they choose the “Sort by: Best” option.
Thanks. That’s interesting. I hadn’t noticed that. They even score higher than some people who posted earlier, and with similar quality posts.
...At first I was going to say I think it would be more of an exponential decrease since most people take the survey in the first few days and I doubt many people diligently keep track of new comments, but then I remembered that the rate of new “I took the survey” comments themselves decrease exponentially, probably at a similar rate, which cancels out much of the effect. Oh well. This does make the situation less unfair.
