I am running into an issue that I can not seem to find a good solution to. I have a right to be forgotten request from an old member which I am attempting to honor. The problem is that their personally identifiable information is not only on their profile but within a number of topics. While I can delete the data, the revision history still contains the data.
A decent example about this is that we have an entire topic related specifically to that person which has numerous pieces of personal information about the individual that I need to be able to permanently and completely delete.
Is there a method I can use to permanently delete that data and have it no longer available even to admins? I would prefer not to have start manipulating the database directly if possible.
