See, if it was my blog I'd have the dilemma to delete or keep this.
Of the types of walls which exist, concrete (hah) and metaphorical, the concrete ones can generally be replaced. Privacy breach is a wall of a kind which is less easy to replace. Does that mean "it's not a wall" ? well.. maybe.
Or maybe not. Metaphors and Analogies suck.
That's not how walls work. Maybe you're thinking of your home and cops or vampires!
