That's... a very ineffective ad then, unless there's some 4D chess move I'm missing. If I see jiberish I just assume it's digital noise and filter it out subconsciously as a shitpost.
Btw not saying this in the sense that I don't believe you of course, just a crazy strategy for an advertisement lol
Edit: Oh wait after reading it again maybe they really thought they were being clever here, but instead pulled a "Don't Dead Open Inside" type of thing? I dont know.
