Those are silent, they’re there for history reasons.

Ohhh! Now I understand!

Yeah, then that’s an issue on mastodon.
I mentioned some time ago, the fact that mastodon and Lemmy use the same protocol is annoying, because the experiences are different, so it causes a lot of issues :/

Unless lemmy devs have changed something since last year, this shouldn’t be the case, there’s a bug in there.

All interactions are recived by the instance hosting the community, and that instance is responsible for broadcasting that interaction to each instance where a user subscribed to it is hosted.
So, mastodon is only responsible for sending the upvote to feddit.dk and then feddit.dk to all other instances.

What?
Well, I can only speak for myself, I’m not here to follow users but communities.
And if someone wants to follow me I’d see it as kind of annoying for them seeing all the different topics I post and comment instead of something focused.

IMO the ability to see Mastodon interactions in Lemmy and vice-versa is quite annoying since they use the same protocol for different experiences.
