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".
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.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: [email protected]
YOU are not a mod btw! "Hallenberg" is. Not you. You probably transfered your ownership to him and did not thought about it. With no mod perms you will not have any mod actions or user action.
Not sure. Depends a lot on context. menu changes depending on how you got there. From the report mailbox links often land me on the poster's instance not logged in. Confusing for sure. Try clicking on the group page link. clicking on the post title works, iirc
