Question

Is it possible to make a Facebook app which edits user’s post on his wall automatically (edits EVERY POST that user makes, app has user’s permission and everything)
I don’t think that’s possible, but maybe I’m wrong?

Answer 1

Based on the Graph API docs, I actually think it could work.

1. Get the extended permission called
   “offline_access”. See
   http://developers.facebook.com/docs/authentication/permissions
2. Periodically pull from
   https://graph.facebook.com/PROFILE_ID/feed
   to see if the user has posted new
   posts.
3. If so, for each new post that has appeared:
4. Pull and store the text of the post.
5. Manipulate the text as desired.
6. Delete the original post using
   “DELETE”. See
   http://developers.facebook.com/docs/api#deleting
7. Publish your modified version of the
   post using “POST”. See
   http://developers.facebook.com/docs/api#publishing
