It seems like there is at least one down vote for every comment that gets enough attention for a few upvotes. I assume there is someone here who just really likes downvoting.

That and, at least on Memmy mobile, you swipe right to upvote and swipe slightly further right to down vote. Also upvote color is orange and downvote color is blue, which is counter intuitive to me personally. So if I get a few downvotes on a comment I think is awesome, I just figure it was an accident and someone was trying to upvote me. Because I’m awesome and who would down vote me?
