When you play videos to earn, do you actually watch them?

So recently I joined iRazoo. I guess I should say rejoined, because I am nearly positive that I was a member years ago. I noticed when I re joined that they had changed a ton of things. Anyhoo, one of the main ways that I earn points/coins or whatever they call the things you have to earn to trade in for gift cards, is by watching videos. I leave them playing in Chrome and half the screen so that I can still do Textbroker and myLot. I will glance at them every once in awhile, but for the most part I don't watch them. There's one playing right now that is teaching how to make a copy cat Chipotle sauce from Subway. There were some animal themed ones earlier which I did watch, but that's because it was actually one of the vlogs that I follow anyway. So the question is, do you watch the videos that you play in order to earn your coinage?
