Yeah. I’m well aware of that, and it’s something I have never done with FaceBook - even though every ow and then it reminds me to do it. Another related problem is that you can’t revoke that permission and remove data that was not obtained through direct input into FB by the data subjects.
This new data protection legislation that]s turning up soon should allow you to be a bit more forceful about having any or all of your data removed. That said, all it takes is for someone else to add you again afterwards....
