For those that are confused, realize Lemmy and Mastodon are two ways of displaying the same ActivityPub information:

• Mastodon "favorite" is a Lemmy "upvote"

• A Lemmy "comment" is a Mastodon "reply"

• A Mastodon post with a mention is a Lemmy post within a community

• A Lemmy "community" on Mastodon appears as a Mastodon account that boosts (retweets) everything that tags (is posted within) it.

• Viewing a Lemmy community from Mastodon shows the entire community (posts and comments) in chronological order. Yes, it's messy but doable.

• Viewing a Lemmy account from Mastodon shows a feed of that user's posts with URLs to the Lemmy instance they were posted to.

• If a Mastodon user mentions a community, that toot gets posted to the community. Replies to the toot appear as comments on Lemmy and replies on Mastodon.

• As others have noted, a toot exceeding a Lemmy instances character limit (200 I think by default) will be cut off on Lemmy and "overflow" into the "body" of the post.

Things that don't directly "translate" AFAIK are the downvote arrow and the community moderator for both of which Mastodon has no equivalent.

"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."

That's not quite right: The Lemmy community boosts the post to the timeline, but not everyone who follows it from Mastodon (or Friendica, Akkoma etc.) receives a notification. The post then only appears in the timeline. You can set whether you want to receive a notification about new posts/boosts from an account

@[email protected] From the ActivityPub perspective (the protocol Mastodon and Lemmy uses), it's interesting how it all ties down. The protocol is fairly generic and doesn't really define what a user or community is, they're all just actors which can map to anything depending on the platform. Mastodon I believe treats all actors like an account. For Lemmy, they can be users or communities. When a post is directed at a community, it becomes a post. For a Wordpress blog, an actor would be an author or some meta actor for the whole blog. How those are interpreted and used is how it gets a little weird sometimes.

The automated account you mention, is it the tagginator bot? If so, well moderation is weird because the post is retracted but the tagginator reply to it which brings it into the Mastodon world is not, so effectively that doesn't mitigate the spam because it's a completely separate account linking to the spam, automatically because it's a bot.

See for yourself here: https://lemmy.ml/post/12065212
I wonder, will this show up as a reply or as a separate post on lemmy?

As a side note, I can't see many of your posts('toots') on my mastodon inst
ance, maly.io, and I had to go to you home instance to see this post, after I saw it on lemmy. Strange.

(P.S. hi @[email protected])

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.

I see it but your subject is just the post contents until it reached a character limit. So it looks like crap.

I'm a random Lemmy user, and I see this as a post on the Lemmy OpenSource community, made by the user u/[email protected]

I agree that it's weird, but I didn't use Twitter much and I don't know what would be a more expected behavior
