When I worked at (pre-IBM) Red Hat, I was explicitly told not to do this, as it would undermine legitimate claims of A/C privilege. I also had one of my machines effectively impounded ("you can add data but don't delete any") for over a year because it might have contained information relevant to ongoing litigation. I wasn't even told what litigation that was, though it was almost certainly patent related, and AFAIK nobody ever looked for any information on that machine. I guess some companies just kind of take their responsibilities more seriously than others.
