It's mentioned here: https://join-lemmy.org/docs/users/03-votes-and-ranking.html so I thought I just didn't notice it before.
My home instance is currently on Lemmy 0.19.0-rc.5, so there's some new features, and I thought this one was here already since it's mentioned on join-lemmy.org.

Anyway, there's also "controversial" in this new version. Currently the most controversial post on Lemmy is this: https://lemmy.world/post/3234363

Sorry if I caused confusion to someone else than myself.

Sounds interesting. Not an option yet on Sync though

It's not sync, it's you're instance's lemmy version. The stable release doesn't include it yet. They're on a release client for 0.19 which should officially launch soon.
