I get that world should be an outlier. World does not have the checkbox, it just says “esto eliminará permanentamente todos sus datos de esta instancia” :) Thought that would include posts etc, but if i understood that right, it was working as intended.

As for the other instances, i did use the checkbox and the accounts etc are gone from the home instance but not anywhere else - at least that is true for the slrpnk account on all the instances that i checked.

Now i’m surprised to find my lemm.ee account is actually gone from lemmy.ml and db0. But it is not from world, slrpnk.net, lemmy.ca, sopuli, blahaj, feddit.org, jlai.lu, discuss.online, infosec.pub, programming.dev, lemmy.nz, but at least something seems to have been federated with this deletion.

I deleted those accounts in late December.

I deleted a newly created account on jlaiu.lu two days ago, they’re running 0.19.5 but i think they have the checkbox (which i have then ticked) and my comment and profile deletion has federated nicely over the instances that i checked.

I would not know how to reproduce all this. I just deleted my accounts and checked the checkbox if it was available.
