Well, you are doing the right thing, and even if they don't reward you with gift cards or T-shirts or anything, at least you're building good karma and whatnot.
Seriously though, companies should reward people who report piracy because it helps encourage people to report that stuff, which is obviously in the company's best interests. Giving out a t-shirt here or a coffee mug there as a reward to loyal fans is a small price to pay for shutting down operations which cost them thousands or millions of dollars in lost sales.
