Looking to leave Lemmy and I’d like to erase my presence here if possible, can this be done? I’ve looked into it and from what I’ve seen, the suggested method is to just not post any more. Which is easy enough, but will I have to manually remove ALL content for all of my accounts in other to remove myself entirely from here?
No. It will not still exist. It can exist.
When a user deletes an account, it federates to other instances. Other instances can ignore this request but by default it will deleted from other instances too.
