No idea - this is something I’ve only just become aware of.

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?

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, @coys@lemmy.world). 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.

Yes, the screenshot is from the menu found in the post.

Thanks very much indeed!

Turns out the best method is to email info@lemmy.world (as recommended in the profile of Ruud). This raises a ticket in their support system.

Think I found where the admins are listed. On https://lemmy.world/ in the sidebar at the bottom the admins are listed.

How do you get on touch with the admins?

That’s my next question too. :)

Is Mastodon compatible with Lemmy?

I’ve been doing this a lot over on https://lemmy.world/c/coys. I mostly post directly from my Mastodon account.

Sometimes I have to jump over and use my Lemmy account because, for example, you can’t post links (that I know of) in the same way you can directly on Lemmy.
