Racism and homo/transphobia, which are often disguised as (mis)information. I don’t usually downvote people unless they’re being outright hateful though and then sometimes I block them too.

Also downvote & report spam, which is actually pretty rare on lemmy.

I use it to order a powerbomb.

I downvote anything that I deem worsens the quality of the community. This includes, but is not limited to:

• misinformation

• trolls

• bad faith engagement

• uncalled for hostility and incivility

• very lazy, low effort posts/comments

“This is so ignorant replying would be a waste of time.”

Misinformation, propaganda, stuff like that. We can disagree and I’ll not downvote you. But if you’re outright spewing lies, whether you realize it or not, I’ll downvote.

“This does not contribute” button.

On a related topic, one thing I learned from the old Century Club days on reddit is the Courtesy Upvote.

If a thread is interesting enough that you commented, upvote it, upvote all the other comments.

If someone replies to you or one of your posts, upvote them too.

Like/Dislike.

It’s a disagree button. That’s how it’s used in practice, and we’re better off just accepting that.

Unhelpful / unconstructive

“I don’t like this” button.
Which is often something I disagree with

misinformation and acting in bad faith, both of which have a funny habit of occuring at the same time

For posts specifically, more juvenile ass, vagina, dick joke/image type posts.

For comments, I tend not to downvote because I normally don’t find a point.

Misinformation, bad attitudes, clichéd jokes

Bad faith, low effort, hostility.
