Apparently you can just copy and paste redacted portions into a different document (Word, Notepad, Docs, etc) and read what is under the redacted text. It feels like this was done on purpose.

If this is the same hack that was going around on X, it only worked on one page.
That is incorrect. You are able to bypass the redactions for a lot of pages in many documents.
This seems to be a full list of all the bypassed redactions:

It doesnt work on all of them though. They probably had different teams doing redactions and some of them did the pdf overlay method which is able to be bypassed.
