How do the crossposts of this post work out? Two are to legit communities with actual people; /c/[email protected] and /c/[email protected]

Three are reddit-promoting bot-communities: /c/[email protected], /c/[email protected] and /c/worldnews@[email protected]

I thought these bot-communities, which are a blight on Lemmy, exclusively post links to reddit. So how is it technically possible two of those bots end up linked together in one cross-post?

Also please shut them down if you can. They flood the network with zero-engagement posts, creating a terrible experience especially for newcomers on the All feed.
