I don't trust the "delete" button to scrub it from FB's database.
I'd be slightly more confident (slightly) that editing the post might cause the core data in the db to be updated, however. In which case, I think the more effective script would be one that goes through all of your FB posts and scrambles them, or replaces the text with gibberish.
