It's a bit extreme to say that it "exists for the sole purpose" of that, since if you look at the post categories, the Facebook-related material only encompasses a small portion of the total posts made.

Regardless of the author's bias towards Facebook, it's possible that they are telling the truth and wall posts that they "deleted" were suddenly made available again due to a flag being unset in the backend or something similar. This is something to keep in mind when creating content on Facebook.
