It took me on average about 3 hours a day for 1.5 weeks to manually use Facebook's "manage posts" bulk deletion tool and even then I didn't get everything deleted, as posts to my wall for my birthday were grouped up and in those groups I could only hide them, with ~1500 friends over 13 years, I opted to hide most of them. At least content I posted was gone.
