That's pretty unfortunate for the blog author, can imagine making that kind of mistake early in the morning will really wake you up.
The blog doesn't mention specifically whether the author had uploaded using a Lemmy app or the webui AFAICT - if he used an app, there are some that actually store the auth/delete token returned by image uploads, and provide a section within the app where you can manage/delete (purge) images you've previously uploaded to Lemmy
Yea i saw the issue on git seems like the devs were rude and assigned you to prove a point. Are you workin on it ? Do yoy even know how or were the devs being dicks on purpose ?
In the future, please use cross post instead and not click bait titles into different communities.
On a more related note, do you have knowledge if the image was federated outwards? Iβm fairly sure Iβve subscribed to that community, so there may be an off chance I have received a copy of the image as part of federation. Is there any way to scour other instances to find images that is federated out and needs to be removed?
