I heard that images can't be deleted from Lemmy instances, due to bugs and various implementation details. Here is an image that has been deleted from the internet, to see if that fixes it.
Edit: I was searching for a "meta" community, since this is a post on Lemmy about current Lemmy limitations... But it turns out that this might very well be off topic. I apologise if it is the case... I would gladly take suggestions on what community would be best for this post, BTW.
Musk allegedly had that imaged deleted from the Internet, while here is an article that highlights the current Lemmytations (pun intended, I know it's bad) wrt image deletion.
This was meant as a joke, since this image allegedly always ends up being deleted, maybe it can fix the issue. 😅
