Facebook – How to Undo Unfollow Actions

You might be able to retrieve it by using the API tools. You first need to get your facebook username.

• You can set your user name or view it if you have already set it by going to http://www.facebook.com/username/

  Note: That this is not the user name you use to log in to Facebook.

You can now use the Graph API you can then retrieve your User Id.

• Browse to https://graph.facebook.com/%YOURUSERNAME% so for instance mine would be https://graph.facebook.com/boconnor

• This will display your user information along with your user id.

• Copy the the User Id - without the quotes.

• Now browse to http://developers.facebook.com/docs/reference/rest/events.get
• Paste your user id in to the uid box and click Call Method
• This will return events that you are linked to.
• Copy the relevent Event EID and browse to http://developers.facebook.com/docs/reference/rest/stream.get
• Enter the EID in to the Source_ids box and click Call Method
• This will return the stream for that event.

I haven't quite worked out a better way of getting all the posts but you can easily copy the details out in to Notepad etc. You can then search through these results for a search term that you used in your comment.

If I can find a better way to get your post on it's own I will post another answer.

Hope this helps

I repeated your steps as follows,

1. Went to Dropbox application page

2. Selected add to page (note, the page is not your profile so you removed it from your profile first time)
   

3. Investigated the app and it was found to be an app that I used to experiment with a page. But notice the app page is not listed as a switch option to use Facebook as a page
   

Head over to the developers section and you will see what app you had forgotten about. I found out that it was an app that I tried to associate with a page but forgot all about it.

So in summary, you added Dropbox to a page of an app that you may have forgotten about.
