How do I delete a post that arrived from Mastodon?

I've got a post in my community that was posted by mistake. This one:

https://lemmy.world/post/4989402

It was actually me that posted it from my Mastodon account.

I can't see a way to delete or hide it from the community.

The kebab menu only has the following items:

  • Create report
  • Block user
  • Lock
  • Community pin

I've tried reporting the post and it appears on the report page, but I don't seem to be able to do anything with it other than clicking "resolve report".

  • I’m not able to help but am curious on how you managed to do it?

    • You can post to Lemmy communities directly from Mastodon (they're both based on ActivityPub). You first follow the Lemmy community in Mastodon, then create a post that mentions the handle for the community (in this case, @[email protected]). The first line of the post becomes the title of the Lemmy post and subsequent lines the body. A little rainbow fediverse icon is displayed on posts that have been federated in from outside of Lemmy.

      It works quite well, but there are a few quirks. You can't attach more than one image, for example, and you can't create URL posts. But replies work both ways, and if you favourite the post in Mastodon, it counts as an upvote. It's pretty neat

      But it seems that posts that arrive via Mastodon can't be moderated? This could be hugely problematic. I mean, posts coming from Mastodon that can't be deleted - what could possibly go wrong? 😅

      Looks like you can block users and instances, but that's not helpful when someone creates a post in error like I did. It's an easy mistake to make: you just mention the Lemmy community's handle.

      • This is really cool, thanks for detailing that out for me. I’ve found something that might help when messing about with it. If you delete the Mastodon post it’s reflected on Lemmy and will be removed. You might still see it as the mod (will have a trash can next to it). Of course that doesn’t help when someone else does, but at least you can remove it for your particular case.

        • Ah, thanks. Yes, deleting it in Mastodon did the trick. It's still far from ideal having no way of hiding/deleting posts from Mastodon other than asking the OP to delete it. This seems like a bit of a gaping security/abuse/moderation hole, no? I'm guessing admins can still delete stuff?

          • Absolutely agree, that could turn into a moderation nightmare if someone wanted to abuse it. Do you know if there's an issue for this on GitHub?
