@[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.
