Genuinely? I think there are always a couple trolls downvoting anything and everything, or people who can't resist being contrarian for the sake of it. I see downvotes applied to on-topic, factually correct, and completely uncontroversial posts and comments all the time. For example, go to any cute animal community. You'll find various inoffensive pictures of the animals, with zero incorrect assertions because it is literally just a picture, and at least a few of these pictures of critters the entire community is about (so it's on-topic) will have a few downvotes anyways. Same principle could apply here. If there are lots of upvotes I almost expect to see a few downvotes as "noise" from trolls.
Also because Lemmy has Local and All, maybe there are people who, not caring that the community is Games, see this in their Local/All feed and do not like video games or Wolfenstein so they just hit downvote for "dislike" and move on.
Sometimes I fat-finger my phone and downvote something I didn't mean to. I always take it back, but I imagine not everyone would undo their accidental downvote. Especially if the sequence is downvote -> crash -> reopen tabs -> wait where was I, whatever I don't care enough to undo one downvote online
I’ve also downvoted things on accident before. Not yet on Lemmy because I have to more deliberately choose through Voyager. But it’s only a matter of time.
You expect Nazis and their sympathizers to have a brain and form coherent sentences, huh?
I fear, there are at least some who do and those are even more dangerous than the typical braindead Nazi.
