The attempt to redact the information is an attempt to protect the innocent. The latest instance of this was a blog post on a Symantec SQL Injection that yielded tons of information including serials and passwords. The image below is a screen capture posted within the blog post.
Next, I visit Google and type: site:symantec.com intitle:Teacher Sima
This is just basic Google Hacking here, nothing advanced. This is something I've been instinctively doing when I see something like this.
So the question is "Why redact?"
