The Great Escape
Got my info off of FB well over a year ago. Goodness they didn't make it easy!
Had to start by shutting down all my friends, so nothing new could be added, then changing all my personal info to question marks.
Let that sit for a few days so those changes could be floated across all their servers. Got back in and started deleting posts. Two pages worth a day, with three of four days between for the system to again, make the changes across their servers, and to give it time to pull up everything it could find.
The best thing about that wall is that it is designed to show you all your comments on your page and the pages of those you've added ad friends as well. As you dig down and delete newer posts, it starts to scour through your friends' lists to find anything you've added and bring them up.
The trick was to just *wait* and let the data - my data - come to me.
Once I got to the point where I was deleting my comments on other people's pages, I knew I was close.
It's those comments you make on *other* people's pages that keeps you in their system.
Once I got everything, I logged out and waited a week to be certain. Sure enough it brought up a few more of the earliest posts I'd made to someone I hadn't even heard from in 4 years. Done.
Once every post was cleared out, I then deleted all my friends (you have to do this last, or you won't be able to get at and remove the posts you've left on their pages) and waited.
Two weeks later, I log in and it is showing me random names of people it *thinks* I might know, not one I actually do.
BINGO! I'm now completely OUT of the system, and maintain the account in my name solely to check on the status of my 'ghost-writer' account, which I use to comment on various sites with.
Have fun shilling my info to whomever you can, Mr. Zukerberg.
