My understanding is that ActivityPub supports a LIKE & DISLIKE attribute which Lemmy uses to create the relability score, like REddit upvote/downvote.
On Soapbox we have like 5 different reacts, and the option to add many many more. I assume 👍 is an upvote, but what the heck is adownvote? could it be 😢 ?
I gave you a downvote so you can see if it registers as anything on your end. I'll switch back to an upvote in a couple minutes so this post still gets visibility.
