Ask HN: Facebook disabled account, how to make sure personal data gets deleted?

Long story short: Facebook has decided to disable my account due to "severe violations of Facebook Community Standards". I have not logged into my account for a half a year and was not active user before then. Recovering account is out of the question, as appeal must be sent 30 days after account was disabled, but nobody actually bothered to inform me about it. No matter, getting rid of Facebook is a win in my book. Now for main question: How do I make sure that all of my personal data gets wiped from Facebook servers? Incidentally the data download fails due to some "technical errors" and I cannot check what personal data is left on Facebook.
