Edit: This isn’t a complaint; just an observation.
Totally random thought, but I see so many people wandering around down voting regular posts that are pretty benign. I also see this a lot on another message board that I’m on.
Disagreeing with people is totally fine, and down voting them as a form of disagreeing makes total sense. But with the nature of some of the posts, down voting just seems completely pointless, so I’m wondering if it’s just trolls going around being negative. 
I’m going to preemptively down vote this post. 
Some people do it to boost their own post by extension. ie: they post, upvote theirs with alt accounts, downvote all others.
