@fediverse Dumb question but do “likes” on #Mastodon automatically create up-votes on a #Lemmy post? I want to get a good grasp on the #Fediverse.

I up voted this from Lemmy, assuming it was posted from Mastodon so you tell me. (It shows 2 rn on my end)
I remember reading (though I can’t find the source anymore) that Mastodon “favorites” and Lemmy upvotes are the same thing, but that it is not possible to downvote from Mastodon.
It’s a bit confusing because each action on the Fediverse uses the same universal language, but each service translates that language into their own specific rolls for their service.
Lemmy upvotes use “Like” which is common language in ActivityPub but down votes use “Dislike” which is
not* also used in the ActivityPub language. It’s up to the other services how they interpret that. Mastodon favourites use “Like” but it has nothing for “Dislike”. Mastodon boost uses “Announce” which is what Lemmy uses for posts and comments to a community.There are also some actions that use the ActivityPub language on both services but one simply just doesn’t send that action to the other service. Mastodon users can follow Lemmy users but Lemmy users cannot follow any users. I think Mbin does allow following users.
From the Lemmy ActivityPub documentation
From the Mastodon ActivityPub Documentation
Dislike is an Activity type defined by ActivityStreams, which is the basis of the ActivityPub vocabulary.
In hindsight, I wrote that line after seeing some code on Github that I thought was for ActivityPub, but when I went back to it later I realised it was for Mastodon.
I’m more confused after reading the responses so far than I was before coming here.
I think the short answer would be yes, because both services translates ‘likes’ the same. However, dislikes does not appear on mastodon.
So this post has (at the time of writing this post):
From this I would say it looks like lemmy upvotes dont federate at all with mastodon. Replies seem to federate but for some reason 1 reply from mastodon is missing on lemmy.
