Unless he has the ad executives' consent it was a bad move posting their full names in the video. Something I've noticed about mavericks (myself included, to a degree) is the willingness to engage is unusual/risky behaviour transcends the generally desirable (given that the "desirable" is classically the usual and proven). Arguing against myself, however, advertising is a fertile home for a maverick.

Generalising the experiment, I'm now curious about soliciting executives for business via this method.
