The federation between mastodon and lemmy is strange. If a M account wants to follow a L community, they need to follow an automated M account which represents the L community. But if any M post mentions that L community, the post will get boosted by the community’s M account, so everybody who follows will get a notification. And I’m not sure if this can be moderated from the L side, because it seems like it never goes through L. Such as - do you see this @opensource ? Does a L mod see this?
It doesn’t look like anybody put a lot of thought into it yet. Look at the title of your post on any Lemmy instance, at least where I’m reading it’s just the first n characters of the text, cut off in mid sentence. Fortunately it’s a work in progress!
The fact that there is some kind of federation is pretty cool but I hope Fedi devs at some point will have the time to implement better (and better formatted 🙂) communication between different instance softwares. It would suck if Lemmy sites just became a sort of red haired stepchild of the larger Fediverse.
