Nice post! I deleted my Facebook account about 2 or 3 weeks ago and I haven't been happier. Before pulling the plug though, I spent a couple days babysitting a post deletion script that wasn't as autonomous as I've hoped. However, I was able to delete my first 3 years and last 5 years of Facebook posts and a decent amount of recent likes/reactions.

I think if you really want to make sure Facebook doesn't have data directly from you, you'd need to take the time to delete every possible interaction you can, delete browser cookies, wait a couple days, then initiate account deletion (Facebook makes you wait 2 weeks until your account is actually deleted, just enough time for you to change your mind).
