On September 4th, 2019, Facebook has changed its API with the result that many research apps accessing public posts are no longer functional. The NodeXL Facebook data importers are also affected by this change.
Our team has requested permission to these API calls and have been rejected. We are applying again just to see if we can get a different outcome. We do not really expect that there will be a change.
If we can not restore access to the Facebook API we will remove the option from the application in an upcoming update.
We regret the loss of this important data source for our users. We note that it is increasingly important to independently understand the nature of social media and Facebook’s decision to restrict access to public data is an obstacle to this goal.
