Well, yes. Until you find out that they are analysing your documents and send you an email explaining why you no longer can access them.

I guess 'noise' does not a photo make.

Of course I doubt they will implement that kind of filtering, but this 'invention' is not that original/difficult/interesting, I guess.

The fact that the original designers did not say anything about this does not mean they did not envision it, by the way. Simply that they may very much either do not care or have a recovery plan.

EDIT: this is obviously easily circumvented with a lot of traffic going on but it is just a simple idea.
