I personally prefer to do it that way--you can create a more convincing review that's more likely to make sales. It's not always possible or practical, though; for example, would you break up with your significant other just to test a product for getting your ex back? ;-) In cases like that, or if the product is expensive, it's usually best just to use the vendor's affiliate resources instead.
I support bootlegging – I don’t see it as being immoral or unethical in any way. I used to bootleg quite a bit in my youth, and I still do on occasion today (although not yet today in particular, I more meant “in the present”). If you want to hustle for your money, do what you must, baby. Download some software, music, movies, or other assorted digital goodness here and start slangin. It’s not an easy life, but sometimes you gotta do what you gotta do.
