* Blanking a page, or part of a page, is an action that any editor can perform, and any editor can undo. This hides content from the "live" page, but anyone can view the blanked content by looking in the page's history. * Deleting a page is an action limited to administrators, and similarly, only an admin can undelete a page. A deleted page is basically treated by MediaWiki like it doesn't exist, and only admins can view the deleted content. Individual edits can also be deleted, but this is not as common. * Lastly, oversighting can be used to hide content from even admins. Admins can oversight stuff as well, and in these cases, the oversighted content can be viewed by other admins, though it requires more work than viewing deleted stuff. For oversighted content to be hidden even from admins, the oversighting must be done by another user group called (aptly enough) oversighters. In the context of WMF project, entry to this usergroup is tightly controlled (seriously, it makes the request for adminship process look like an open door), and anyone selected for the role must personally confirm their identity to the WMF.
The main point is that, in all of these cases, the content is never gone, but simply hidden; the MediaWiki software is designed so that every action is logged and can be reversed.
For instance, a common obfuscation method is simply removing the magic number from the file; in this case, the program may simply try to use the file as the given format and return an error (or crash; we are talking largely about proprietary software in these cases after all) if the file can't be read.
Other than that, I can't provide any information on file formats allowed to start at offsets other than 0, or why this may or may not be a good idea (I suppose maybe it would allow an enterprising programmer to hide a malicious file by embedding it in an otherwise-innocuous format?), though I am certainly curious as well.

300 terabytes for $350? In one drive? Sign me up. =D

[1] I talk about the American licensors, industry, and fanbase here, but much of what I say is more-or-less directly applicable to the same in other countries, as well.
[2] Just so we're clear, I'm being sarcastic here. There's absolutely no reason to believe that if you treat someone with respect, they're going to turn around and hate you for it. There are cases where this happens, of course (and this response may be more or less likely then normal depending on the nature and reasons for your interactions with them), but it's by far the exception.
Simply adding more costs onto gas is going to do nothing more to change what the average US citizen drives then what the past decade of price increases have.
* This is based on anecdote and recollection; I don't have any sources to back it up, but if it's wrong one way or the other, more than likely it's conservative.
I am not saying the current situation is ideal, but it is better by leaps and bounds than what it used to be, and what you are proposing.
In retrospect, I probably should have kept my thoughts to myself, and I probably deserve the downvote or two that I got for not doing so. =)
Of course, I don't have much firsthand knowledge of computational complexity myself, so someone else who know better should call me on any nonsense above. =D
