Just a couple of things to get straight:
1. I have been trying for days to back up these files; it didn’t just now dawn on me that I needed to do that.
2. Let’s assume that I am a terrorist or criminal of some sort, and I post something that the Homeland Security people would take an interest in. Are you telling me that, once I cancel the domain, the Dept of Homeland Security has no access to the files? That WordPress doesn’t have a backup somewhere that they could produce if a person knew how to ask right?
