I deleted my accounts on other instances. One of them indeed is seen as empty (so fine by me), but the other one still has all my posts on from the perspective of my new instance.

I deleted them at about the same time, both on different instances. One is empty, from perspective of my new instance, but the other one shows all the posts. What am I supposed to do? I share some of my personal stuff online as means of venting so I can possibly reflect through unbiased responses from strangers and I'm comfortable with it, as long as I have control over my "content", so to speak. I'm not sure what to do now.
