But you can often tell. If they're doing it for the money there's no passion just like with regular porn or any other form of creative expression. The best do it because they love it, and are very thankful for the money.Some are doing it just for the money.
I do agree that many get into porn because of the money and end up loving it. But there's not that much money in bestiality porn. The ones making the money are the guys running the sites posting pirated videos since they don't have to pay anyone.
