While it's understandable that to get something deleted from Internet is next to impossible that's because there's no Internet Inc. But Facebook is a monolithic network with full control of its walled garden.

It is pretty clear they are not interested and letting us really manage what we posted on its walledgardn. There's no way for me to mass delete/edit posts on facebook. Yes, facebook did not force me to post things 10 years ago but it seems like they are forcing me to hold my own post against me for eternity unless I spend years of my time to go through one post at a time.

Delete facebook profile? well it doesn't really delete it: https://www.quora.com/When-you-permanently-delete-your-Faceb...
