But, worse, it makes it sound like it's only something you should use if you don't trust the other person.
Instead, they should market it as "2fa for sex tapes" rather than a trust issue by itself and point to things like "the fappening" icloud social engineering hack.
I can't imagine many people using this otherwise.
Also, don't forget that your target audience is mostly women who bear the majority of the shaming for a leaked video instead of high-fives. "Don't be the next Jennifer Lawrence" is going to be more effective marketing.
